The Gladiator on the Cross

He stirs up the people by teaching throughout all Judea, from Galilee where he began even to this place. When Pilate heard this, he asked whether the man was a Galilean. And when he learnt that he was under Herod's jurisdiction, he sent Him off to Herod, who was himself in Jerusalem at that time. When Herod saw Jesus he was very glad for he had been wanting to see Jesus for a long time, because he had heard about Him and was hoping to see Him perform some sign. He questioned him at some length, but Jesus gave him no answer. The chief priest and the scribes stood by vehemently accusing Him. Even Herod with his soldiers treated Him with contempt and mocked Him.                                                                           

                                                                                                                                                                                            Luke 23: 5 - 11              


The below essay on the Passion of Christ is based on the authors understanding of the events that unfolded on that day. Except for Jesus and His Mother Mary, (our Mother of Perpetual Help), any resemblance to the fox and to any of the characters in the essay is unintentional. The essay is inspired from the gospels of Mathew, Mark, Luke and John and can be open to questions and to debate.                                               

Jesus was going about all of Jerusalem healing the sick. The blind were receiving their sight, the lame were walking, the leapers were cleansed, the deaf began to hear, the dead were raised to life, the poor were listening to the good news of the Kingdom of God. Thus large crowds were following Jesus and they wanted to take him by force and make him King. News about his deeds and his teachings were spreading all around Jerusalem. It had also reached the ears of the chief priests, the scribes and the pharisees who were beginning to get more and more envious of the growing popularity of the so called Messiah. 

The chief priests began to discuss among themselves how the accused by claiming to be King was challenging the Emperor's authority. Letting him off would be detrimental to the Emperor and to their authority as priests and authorities of the temple. He was drawing the people to Himself by his teaching, healing and the miracles he was performing. Soon there would be an uprising and a revolt against the authorities, the people would start complaining about the heavy burdens being put on their backs by the lawyers, scribes and pharisees, the unjust system of taxes and many other evils happening in the society in the name of the law. The people would stop going to the synagogues and the temples. The temple tax and donations to the temple and synagogues would dry up. They would be in a state of anarchy and lawlessness. Eventually the Romans would come and destroy both their nation and their Holy places. So Caiaphas who was high priest that year stated that it was better to have one man die than to have the whole nation destroyed. So from that day they planned to put Jesus to death. 

After trying several times to trap Jesus and arrest Him, they finally found an opportunity when Judas offered to betray Jesus for the price of thirty pieces of silver. In the garden of Gethsemane, when Jesus was praying with his disciples Judas arrived with the police of the authorities, and a crowd of scribes, chief priests and elders carrying swords and clubs. On seeing Jesus in the garden, Judas went over to Him and kissed Him. Ceasing the opportunity, the soldiers caught hold of Jesus and arrested Him.

They brought Jesus before Caiaphas the High priest. The scribes and the elders were also gathered there. Among them there were many false witnesses who came forward to give false testimony against Jesus. Then Caiaphas asked Jesus about the accusations being brought against Him and about the work he was doing. But Jesus remained silent. Then the high priest asked Him again, "I put you under oath before the living God, tell us if you are the Messiah, the Son of the living God.' Jesus said to Him, 

"You have said so, but I tell you, from now on you will see the Son of Man, seated at the right hand of power and coming on the clouds of Heaven.
I have spoken openly to the world; I have always taught in synagogues and in the temple, where all the Jews comes together. I have said nothing in secret. Why do you ask me. Ask those who have heard what I said to them; they would know what I said"

Then the high priest, who was waiting for this opportunity, tore his clothes in a grave display of piousness, and said, "He has blasphemed! Why do we need witnesses? You have now heard his blasphemy. What is your verdict?" They answered, "He deserves death". Then they spat on His face and slapped Him saying, "Prophesy to us, you Messiah! Who is it that struck you?" One of the police who had arrested Jesus, and who was standing nearby, struck Jesus on the face saying, "Is this how you answer the high priest?"

Jesus answered, "If I have spoken wrongly, testify to the wrong. But if I have spoken rightly, why do you strike me?"

Then they took Jesus from Caiaphas to Pilate's headquarters. It was early in the morning.

While Pilate was seated on the judgement seat the chief priests and the scribes brought chief priests brought Jesus before him. They began to accuse Jesus before Pilate saying that he claimed to be the Messiah and many other false accusations. Pilate listened to all these accusations and then asked Jesus, "Are you the King of the Jews?" Jesus answered, "Do you ask this of your won accord, or did others tell you about me?" To this Pilate replied, "I am not a Jew, am I? Your own nation and chief priests have handed you over to me. What have you done?" Jesus answered, "My kingdom is not from this world. If my kingdom were from this world, my followers would be fighting to keep me from being handed over to the Jews. But as it is my kingdom is not from here." Pilate said to him, "So you are a King?" Jesus answered, "You say that I am a King. For this I was born and for this I came into the world, to testify to the truth. Everyone who belongs to the truth listens to my voice". Pilate asked Him "What is the truth?" Jesus remained silent. Pilate still found no basis against the man that deserved the death sentence. Earlier his wife had sent word to him, "Have nothing to do with that innocent man, for today I have suffered a great deal because of a dream about Him." He realized that it was out of jealousy that the chief priests and scribes were accusing Him and was wary of passing judgement on Him. Now since Jesus was a Galilean and he came under the jurisdiction of Herod, he sent him to Herod to be judged.

Jesus was now before Herod the tetrarch, The Governor of Galilee. The chief priests and scribes had accompanied Him to Herod's palace with a band of soldiers. Herod was waiting since a long time for this day when he would see the self proclaimed God man who was doing many miracles and healing people, raising the dead to life and gathering a large following of people by his teachings and his healings. The chief priests placed their accusations before Herod and were vehemently condemning Jesus before him. But Jesus remained silent through all these accusations without saying a word in his defense. Herod then asked Jesus, that if he were the Messiah, the Son of God, that he perform a miracle, to show some sign to prove his divinity. But Jesus again remained silent. Herod was perplexed and annoyed. Here he was brought before him with a charge of blasphemy, and the accused was doing nothing to defend Himself. On the contrary, his silence was like a resigned acceptance of the penalty that faced such a claim. The chief priest and elders were waiting expectantly for Herod to pass the death sentence on the accused. But Herod suddenly burst out into a loud laughter. This puzzled the chief priests. It was a loud boisterous laugh which was soon picked up by his people the soldiers present in the room. They began to mock Jesus. He had claimed to be the Messiah, but here he was standing silent and resigned in the face of death.  Surely Herod was not going to waste his time or his judgement on this meek silent man standing in front of him. He didn't feel any threat to his kingship by this man. If the accused was not going to perform any sign to prove his divinity, if he was not going to defend himself against the accusations being brought against Him by his own people, neither was Herod going to pass any judgement on Him. He simply dismissed the accused. If He was truly the Son of God, he would have to save Himself by His own divine powers.

The chief priests and the scribes now realized that they were cornered. They were trapped at their own game. They made laws which put heavy burdens on the backs of people, but they themselves would not lift a finger to move these burdens or help the people. They would accuse people of crimes deserving the death penalty, but they themselves would not pass the death penalty. They didn't realize that in Herod they were dealing with the Master of the Game. The fox was more crafty than they had imagined. They now had to figure out a way to crucify the condemned man without breaking their own laws.

The Game of Kings was now in its last stages. The rooks, the knights and the vazirs, the defenders of the kingdom, were all killed over the centuries. The pawns were decimated in their infancy. The last knight standing was beheaded by none other than Herod himself.

The Oracle Story

                              No one after lighting a lamp puts it under the bushel basket, but on the lampstand, and it gives light to all in the house
                                                                                                                                                             Mathew 5:15

Oracle corporation, initially called Software Development Laboratories, was founded in 1977 by Larry Elison and Bob Miner, computer programmers at Ampex Corporation, an American electronics company along with Ed Oates, Elison's supervisor at Ampex. The idea for the relational database was inspired by a paper by Edgar F Codd that outlined a relational model. They had the vison of making this data management concept commercial as it arranged large amounts of data efficiently and also enabled quick retrieval. Thus the trio started developing the program based on Codds theory and in 1979 the company released Oracle, the earliest commercial relational database program using structured query language. 



Once he learned the skills and concepts for relational databases Larry Ellison began to pursue his dream to start a data management company now know as Oracle. In the early years it was in competition with IBM which was also in the race to develop a relational database at that time. The IBM database is IBM DB2. But of the two Oracle is more widely used and popular.

Its first customer was the US Air Force which used the program at its air force base.

Oracle has grown from its humble beginnings as one of a number of databases available in the 1970s to the overwhelming market leader today.

In 1978 the first Oracle software was born, written in assembly language running on PDP-11 under RSX-11 in 128K memory. The first Oracle version was never released and the implementation separated oracle code from user code. The name Oracle came from the code name of a CIA project that the three original founders Elison, Bob and Ed had worked on in Amex Corporation.



In the year 1979,they offered the first commercial SQL relational database management system. The second version of Oracle released ran on PDP-11 hardware and they named it as Oracle v2 to capture more customers and they starting promoting it on the VAX platform.
In 1984 the database software was ported to the PC platform with the MS-DOS version 4.1.4 running on 512K memory.
In 1985 it was released to operate in client-server mode.

Initial funding was through personal funding of its founders and Venture Capitalists and it went public in 1986 and was then financed through its IPO and since then it has not raised any additional funds through Venture Capitalist or private investors.

In 1987 UNIX-based Oracle applications were introduced and a year later Oracle v6 was released with hot backups, embedded PL/SQL procedural engine within the database and support for row-level locking. In 1988 Oracle induced PL/SQL. The growth in the company led to relocation of the world headquarters to Redwood Shores, California in 1989 and revenues reaching $584 million.

In 1989, Oracle moved its headquarters to Redwood City, California. 

In 1995, Oracle Systems Corporation changes its name to Oracle Corporation and it became the first large software company to report an internet strategy and offered the first 64-bit RDBMS.
In June 1998 Oracle v8 was released with internet technology, support for terabytes of data and SQL object technology. 

In 1998 they announced integrating a JVM with the oracle database and in September of that year Oracle 8i was release, with i standing for internet. 
In 1999 Oracle offered its first DBMS with XML support.

In 2010 Oracle Corporation acquired Sun Microsystems After the merger Oracle owned Sun's hardware product lines as well as Sun's software product lines including the JAVA programming language.
My tryst with JAVA

Oracle Corporation has now diversified into a range of services like Oracle cloud services, Oracle middleware, Oracle Beehive, Financial services, hardware systems etc.
Middleware includes weblogic server which is a J2EE server and Oracle fusion middleware.
Oracle applications include ERP, CRM and Human Capital Management HCM.
Cloud services include SaaS Software as a service, PaaS Platform as a Service, IaaS  Infracture as a Service and DaaS Database as a Service.

God's Word for the day

The Evil Tongue
If you blow on a spark it will glow;
  If you spit on it, it will be put out;
Yet both come out of the mouth.
  Curse the gossips and the double-tongued,
For they destroy the peace of many.
  Slander has shaken many, 
And scattered them from nation to nation.
  It has destroyed strong cities
And overturned the houses of the great.
  Slander has driven virtuous women from their homes,
And deprived them of the fruit of their toil.
Sirach 28:12 - 15

Gospel teachings of Jesus

Jesus curses the fig tree
In the morning, when he returned to the city,
  he was hungry. And seeing a fig tree by the
side of the road, he went to it and found nothing
  at all on it but leaves. Then he said to it,
"May no fruit ever come from you again!"
  And the fig tree withered at once. When the
disciples saw it they were amazed, saying,
  "How did the fig tree wither at once?" Jesus
answered them, "Truly I tell you, if you have
  faith and do not doubt, not only will you do
what has been done to the fig tree, but even if
  you say to this mountain, 'Be lifted up and 
thrown into the sea .' it will be done.
  Whatever you ask for in prayer with faith,
you will receive."

React For Web Development

                                                                                                              The fear of the Lord is the beginning of knowldege                                                                                                                                                             Proverbs 1:7 

What is React?

React is an external library used for web development. It is a powerful JavaScript used for building modern, fast and interactive user interfaces. It uses virtual DOM to update only specific parts of the screen that need to change.

To create and run react pages, the three basic requirement would be

  • a code editor to write the code. Download Visual Studio Code code editor.
  • a browser to run and view the page created in react. Google Chrome or Mircosoft edge.
  • a runtime environment (node.js) to run the development server. Node.js automatically installs npm (Node Package Manager) which handles installing the React library and project dependencies. Download Node JS

Creating Your First React web page.

Create a local folder say "D:\java\react_course".

In this folder create and save the below html code.

react-basics.html

<!DOCTYPE html>
<html>
  <head>
    <title>React Basics</title>
  </head>
  <body>
    <div class="js-container"></div>
    <script>
      console.log('hello world');
    </script>

    <script src="https://unpkg.com/supersimpledev/react.js"></script>
    <script src="https://unpkg.com/supersimpledev/react-dom.js"></script>

    <script src="https://unpkg.com/supersimpledev/babel.js"></script>
    <script type="text/babel">
      const container = document.querySelector('.js-container');
      ReactDOM.createRoot(container).render(<h1>Welcome to SuperSimpleDev React Course</h1>);
    </script>
  </body>
</html>

To edit this code, Open Visual Studio Code and File->Open Folder-> D:\java\react_course.

To run the react page, open react-basics.html in the chrome or edge browser.

To see the javascript 'hello world', in the browser, right click and inspect and in the Console tab you can see the javascipt log statement.

You can also load javascript code from a .js file or from a any site on the internet.

Example to load javascript code from a .js file.

<script src="react-basics.js">
      <!-- console.log('hello world'); -->
</script>
Example to load javascript code from the internet.
<script src="https://unpkg.com/supersimpledev@8.6.4/external-library.js">
      <!-- console.log('hello world'); -->
</script>
The output on Console table when you reload the page and inspect is
console.log('This is an external library.');
Thus we see different ways how we can run javascript code in react.

Understanding the Basic React Code

The next two lines of the react code are loading the react libraries to run react web pages.

<script src="https://unpkg.com/supersimpledev/react.js"></script>
<script src="https://unpkg.com/supersimpledev/react-dom.js"></script>
If we load both these urls in a browser you can see the javascript code for react.
react.js and react-dom.js are used for creating websites.
react.js  and react native js are used for creating mobile applications. 
<script src="https://unpkg.com/supersimpledev/babel.js"></script>
    <script type="text/babel">
      const container = document.querySelector('.js-container');
      ReactDOM.createRoot(container).render('Welcome to SuperSimpleDev React Course');
</script>
This snippet of code loads the babel javascript compiler.
The script element "text/babel" indicates that the code inside that element is .jsx code and instructs babel to transform or compile it to standard javascript that browser engines can understand.
document.querySelector searches your HTML file for an element with the class name js-container and saves is in an element called container. This is because react needs a spot on the webpage where it can safely inject and display its content.
ReactDOM.createRoot takes the HTML element (container) and initializes it as a React Root.  
.render injects the content inside the () into the root element. Which is then displayed on the browser.

Rendering to HTML
The code which babel compiles so that the browser can run it is as below
const container = document.querySelector('.js-container');
ReactDOM.createRoot(container).render(
  React.createElement('h1', null, 'Welcome to SuperSimpleDev React Course')
);
In this, the browser's DOM API is used to locate the CSS class element (js-container) in your HTML page. This element serves as the mount point.
ReactDOM.createRoot creates a root instance (manager) attached to that DOM element  (container) which manages the virtual DOM and handles scheduling, updating and rendering UI efficient components inside container.
React.createElement() returns a lightweight JavaScript object describing the UI element as shown in the javascript below.
.render takes this element and mounts it into the DOM.

JavaScript
{
  type: 'h1',
  props: {
    children: 'Welcome to SuperSimpleDev React Course'
  }
}
React then uses the standard browser APIs namely document.createElement('h1') and document.createTextNode(...) to create DOM nodes in memory.
Finally, React appends the newly created <h1> node inside your target container.
The final HTML code which is created in the browser's HTML DOM is
<div class="js-container">
  <h1>Welcome to SuperSimpleDev React Course</h1>
</div>
Sample code to add and render a paragraph on your browser page
const paragraph = <p1>paragraph of text</p1>
const container = document.querySelector('.js-container');
ReactDOM.createRoot(container).render(paragraph);
Sample code to add and render a button element on your browser page
const button = <button>Submit</button>
const container = document.querySelector('.js-container');
ReactDOM.createRoot(container).render(button);

God's Word for the day

Anger and Vengeance
Refrain from strife and your sins will be fewer;
  For the hot tempered kindle strife,
and the sinner disrupts friendships. 
  and sows discord among those who are at peace.
In proportion to the fuel so will the fire burn,
  and in proportion to the obstinacy, so will strife increase.
In proportion to a person's strength will be his anger,
  and in proportion to his wealth he will increase his wrath.
A hasty quarrel kindles a fire, and a hasty dispute sheds blood.
Sirach 28:8 - 11

Gospel teachings of Jesus

Jesus' Triumphal Entry into Jerusalem
When they had come near Jerusalem and had reached Bethphage, 
 at the Mount of Olives, Jesus sent two disciples, saying to them,
"Go into the village ahead of you, and immediately you will find
  a donkey tied, and a colt with her; untie them and bring them to me.
If anyone says anything to you, just say this, 'The Lord needs them.'
  And he will send them immediately. This took place to fulfill what
had been spoken through the prophet saying,
"Tell the daughter of Zion, 
   Look your king is coming to you,
humble and mounted on a donkey,
  and on a colt, the foal of a donkey"
The disciples went and did as Jesus had directed them; they brought
  the donkey and the colt, and put their cloaks on them, and he sat on
them. A very large crowd spreak their cloaks on the road, and others 
  cut branches from the trees and spread them on the road. The crowds
that went ahead of Him and that followed were shouting,
  "Hosanna to the Son of David!
    Blessed is the one who comes in the name of the Lord!
    Hosanna in the highest heaven!"
When he entered Jerusalem the whole city was in turmoil, asking,
  "Who is this?" The crowds were saying, "This is the prophet 
Jesus from Nazareth in Galilee."

God's Word for the day

Hypocrisy and Retribution
Whoever throws a stone straight up throws it on his own head,
  and a treacherous blow opens up many wounds.
Whoever digs a pit will fall into it,
  and whoever sets a snare will be caught in it.
If a person does evil, it will roll back upon him,
  and he will not know where it came from.
Mockery and abuse issue from the proud,
  but vengeance lies in wait for them like a lion.
Those who rejoice in the fall of the godly
  will be caught in a snare.
And pain will consume them before their death.

and said to them on the way, "See, we are going up
  to Jerusalem, and the Son of Man will be handed
over to the chief priests and scribes, and they will
  condemn him to death; then they will hand him
over to the gentiles to be mocked and flogged and
  crucified. and on the third day he will be raised."

Gospel teachings of Jesus

The laborers in the vineyard
For the kingdom is heaven is like a landowner
  who went out early in the morning to hire laborers
for his vineyard. After agreeing with the laborers for
  the usual daily wage, he sent them into his vineyard.
When he went out about 9 O 'clock, he saw others 
  standing idle in the market-place; and he said to them,
'You also go into the vineyard, and I will pay you 
  whatever is right. So they went. When he went out
again about noon and about three O 'Clock, he did the
  same. And about five  O 'clock he went out and 
found others standing around; and he said to them. 'Why
  are you standing here idle all day?' They said to him,
'Because no one has hired us.' He said to them, 'You also
  go into the vineyard.' When evening came the owner of
the vineyard said to the manager, 'Call the laborers and 
give them their pay, beginning with the last and then going
  to the first.' When those hired about five O 'clock came, 
each of them received the usual daily wage. Now when 
  the first came, they thought they would receive more,
but each of them received the usual daily wage. And when
  they received it, they grumbled against the landowner
saying, 'These last worked only one hour, and you have 
  made them equal to us who have borne the burden of the
day and the scorching heat.' But he replied to one of them,
  'Friend I am doing you no wrong; did you not agree with
me for the usual daily wage? Take what belongs to you and
  go; I choose to give to this last the same as I give to you. 
Am I not allowed to do what I choose with what belongs to
  me? Or are you envious because I am generous?' So the
last will be first and the first will be last."
Mathew 20:1 - 16

The Spring Framework

 The spring framework is a lightweight framework used to build scalable, maintainable enterprise applications.  It works on the principle of Inversion of Control. (IoC).

What is Inversion of Control?

It refers to the reversal of flow of control in a program. In this the control is shifted to an external entity (the IOC container in case of Spring) that manages the creation and injection of dependencies. The IoC container creates and wires the objects together, allowing objects to focus on their main responsibilities.

In normal flow, a program's custom code calls reusable libraries to take care of generic tasks, but with IoC it is the framework that calls the custom code. In essence, this means delegating execution of tasks to generic code instead of specific code allowing for more versatility. It carries the philosophy that reusable code and problem specific code be developed independently even though they operate together in an application.

Inversion of Control can be achieved through dependency injection, callbacks, schedulers, event loops to name a few methods. We will discuss more deeply on Dependency Injection.

Dependency Injection.

Dependency injection is a design pattern used to remove manual hard coded dependencies in classes by externalizing the creation and management of objects (dependencies). 

Instead of an object creating its dependencies itself, it relies on an external entity (the container) to provide the required dependencies. DI promotes loose coupling and improves the flexibility and testability of the code. The dependency injection (DI) pattern is one of the ways to implement IoC. 

The Spring container handles all the object instantiation and initialization and injection in the right places.

The Spring Bean is an object that is created and managed by the Spring IoC container.

Thus the Spring IoC container acts like a bag of beans and is responsible for

  • Bean creation, maintenance and deletion. - The container reads the bean definitions (from the XML files or annotations), creates the bean instances and manages their life cycles.


The Spring IoC Container

The Spring container uses IoC to manage the objects (Spring Beans) that make up an application. The container gets its instructions on what objects to instantiate, configure and assemble by reading the configuration metadata provided. This configuration metadata can be either an XML file, Java annotation or Java code. The container makes use of Java POJO classes and configuration metadata to produce a fully configured and executable system or application.




There are two distinct types of containers that the Spring Framework provides.
  • The Spring BeanFactory Container
  • The Spring ApplicationContext Container.

The BeanFactory Container - This container provides the basic support for DI and is defined by org.springframework.beans.factory.BeanFactory interface. The BeanFactory and related interfaces, such as BeanFactoryAware, InitializingBean, DisposableBean, are still present in Spring for the purpose of backward compatibility with a large number of third party frameworks that integrate with Spring.

The key features of the BeanFactory are

  • Lazy Initialization : Beans are created only when explicitly requested.
  • Lightweight : Minimal memory usage, suitable for resource-constrained environments.
  • Basic Bean Management : Supports bean instantiation, configuration, and lifecycle methods like init and destroy.
Example :

// Using BeanFactory (rarely used directly in modern Spring apps)
BeanFactory factory = new XmlBeanFactory(new ClassPathResource("beans.xml"));
MyBean bean = factory.getBean(MyBean.class);

The ApplicationContext Container - This container adds more enterprise specific functionality such as the ability to resolve textual messages from a properties file and the ability to publish application events to interested event listeners. This container is defined by the org.springframework.context.ApplicationContext interface. This container includes all the functionality of the BeanFactory container and so in recommended over BeanFactory container.  Thus ApplicationContext is a superset of the BeanFactory and is the preferred choice for Spring Boot applications. It extends BeanFactory to add enterprise specific features, making it more powerful and developer friendly.

Key Features

  • Eager Initialization - Beans are configures at startup (unless explicitly configured as lazy.)

Enterprise Features

  • AOP Integration - Built is support for Aspect-Oriented programming.
  • Event Handling - Publishes and listens to application events. (eg. - ContextRefreshedEvent).
  • Internationalization (i18n) : Supports message resource handling for multilingual apps.
  • Resource Loading: Access to files, URLs and classpath resources.
  • Annotation Support: Auto detects @Component, @Autowired etc.

Example

// Using ApplicationContext (common in Spring Boot)
ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
MyBean bean = context.getBean(MyBean.class);
ApplicationContext is used in most modern Spring Boot applications especially in apps requiring advanced features like events, AOPs, or resource handling.
SpringBoot simplifies configuration by automatically creating and configuring an ApplicationContext.
It uses AnnotationConfigApplicationContext for Java based configuration (Default behavior)
and AnnotationConfigServletWebServerApplicationContext for web apps.
Use ApplicationContext  unless you have a specific reason to use BeanFactory. 
Use annotations like @Bean, @Configuration, @ComponentScan and @Configuration etc instead of XML configuration.

God's Word for the day

Hypocrisy and Retribution
Whoever winks the eye plans mischief
    and those who know him will keep their distance.
In your presence his mouth is all sweetness
    and he admires your words;
But later he will twist his speech, and with your
    own words he will trip you up.
I have hated many things but him above all;
    even the Lord hates him
Whoever throws a stone straight up throws it on his own head
    and a treacherous blow opens up many wounds.
Whoever digs a pit will fall into it,
    and whoever sets a snare will be caught in it.
If a person does evil it will rollback on him
    and he will not know where it came from
Mockery and abuse issue from the proud,
    but vengeance lies in wait for them like a lion.
Those who rejoice in the fall of the godly will be caught in a snare
    and pain will consume them before their death.
 
Sirach 27:22 - 29

Gospel teachings of Jesus

The laborers in the vineyard
For the kingdom of heaven is like a landowner who went out
     early in the morning to hire laborers for his vineyard.
After agreeing with the laborers for the usual daily wage,
    he sent them into his vineyard. When he went out about
nine O' clock, he saw others standing idle in the marketplace.
    and he said to them, 'You also go into the vineyard and I will
pay you whatever is right. So they went. When he went out 
    again about noon and about 3 O 'clock he did the same. And
about five O'clock he went out and saw others standing around,
    and he said to them, 'Why are you standing here idle all day?'
And they said to him, 'Because no one has hired us.'
    He said to them, 'You also go into the vineyard.' When evening
came the owner of the vineyard said to the manager, 'Call the
    laborers and give them their pay, beginning from the last and
going to the first.' When those hired about five O' clock each of 
    them received the usual daily wage. Now when the first came
they thought they would receive more; but each of them received
   the usual daily wage.  Now when the first came
