Bereshit 4

And Adam lay with Eve his wife; and she conceived and bore Cain. And she said: 'I have been provisioned with a man from before God.'

Then she repeated, and bore his brother Abel; and Abel was a shepherd of sheep, and Cain was a tiller of the earth.

And after days had passed, Cain brought from the fruit of the earth a gift to God.

And Abel — he too — brought from the firstborn of his sheep and from their fatlings; and God accepted Abel and his gift.

But Cain and his gift He did not accept; and it pressed greatly upon Cain, and his face fell out of shame.

And God said to Cain: 'Why has it pressed upon you, and why has your face fallen?

Is it not so — if you do well, you shall be accepted; but if you do not do well, then wherever you turn, your sin is crouching; and toward you is its inclination — yet you are the one set in authority over it, by free choice.'

Then Cain quarreled with Abel his brother; and when they were in the wilderness, Cain rose up against Abel his brother and killed him.

And God said to him, by way of confirming: 'Where is Abel your brother?' He said: 'I do not know. Am I the keeper of my brother?'

He said: 'What is this that you have done? The voice of the blood of your brother cries out to Me from the earth!

And now you are cursed from the earth, which opened its mouth and received the blood of your brother from your hand.

When you till it, it shall not again give you its strengths; a wanderer and a roamer shall you be in the earth.'

And Cain said before God: 'My sin is greater than can be forgiven.

If You expel me today from the face of the earth — can I be concealed from before You? And if I be a wanderer and a roamer in the earth, every one who finds me shall kill me.'

And God said to him: 'Therefore, every one who kills Cain — vengeance shall be exacted by means of him many times over.' And God set for Cain a sign, that no one finding him should kill him.

And Cain went out from before God, and settled in the land of Nod, east of Eden.

And Cain lay with his wife; and she conceived and bore Enoch; and he built a town, and named it after the name of his son, Enoch.

Then to Enoch was born Irad; and Irad begot Mehuyael; and Mehiyael begot Methushael; and Methushael begot Lamech.

And Lamech took for himself two wives; the name of one of them was Adah, and [the name of] the other was Tzillah.

And Adah bore Yaval; he was the first to dwell in tents and possess cattle.

And Tzillah, she too, bore Tuval-Cain; and he was the first burnisher of every craft of copper and iron; and his sister was Naamah.

And Lamech said to his wives, with confidence: 'Adah and Tzillah, hear my voice; O wives of Lamech, give ear to my speech: have I killed a man by my striking, or a child by my wounding?

If vengeance for Cain be much, then for Lamech more and more.'

And Adam lay again with his wife; and she bore a son, and named him Seth. She said: 'God has provisioned me with another offspring, in place of Abel — since Cain killed him.'

And to Seth, too, a son was born; and he named him Enosh. At that time, the calling upon the name of God was profaned.
