And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD.

And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.

And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD.

But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.

And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen?

And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.

And the LORD said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother's keeper?

And Cain said unto the LORD, My punishment is greater than I can bear.

And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.

And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.

And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch.

And Zillah, she also bore Tubal-Cain, the forger of every kind of tool of brass and iron. And the sister of Tubal-Cain was Naamah.

If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.

And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew.

For if Cain shall be for consuming, how long shall Assyria take thee captive?

Cain, Gibeah, and Timnah; ten cities with their villages:

Let his children wander and beg;
Let them seek their food and be driven far from their ruined homes.

You belong to your father the devil, and you are [always] wanting to do what your father desires. He was a murderer from the [very] beginning [Note: This is probably a reference to Satan's influence on Adam, Eve and Cain in the Garden of Eden] and does not stand for the truth, because there is no truth in him. When he lies, he only speaks what is part of his nature, because he is a liar and the father of [all] liars.

By faith Abel offered unto God a more excellent sacrifice than Cain, through which he had witness borne to him that he was righteous, God bearing witness in respect of his gifts: and through it he being dead yet speaketh.

for this is the injunction which ye heard from the beginning, that we should love one another: not as Cain who was of the evil one, and slew his brother;

not as Cain was of the evil one, and slew his brother. And wherefore slew he him? Because his works were evil, and his brother's righteous.

Woe be unto them, for they have followed the way of Cain, and are utterly given to the error of Balaam for lucre's sake, and are cast away in the treason of Korah.
