Cain

The man had sexual relations with Havah his wife; she conceived, gave birth to Kayin [acquisition] and said, “I have acquired a man from Adonai.”

In addition she gave birth to his brother Hevel. Hevel kept sheep, while Kayin worked the soil.

In the course of time Kayin brought an offering to Adonai from the produce of the soil;

but did not accept Kayin and his offering. Kayin was very angry, and his face fell.

Adonai said to Kayin, “Why are you angry? Why so downcast?

Kayin had words with Hevel his brother; then one time, when they were in the field, Kayin turned on Hevel his brother and killed him.

Adonai said to Kayin, “Where is Hevel your brother?” And he replied, “I don’t know; am I my brother’s guardian?”

Kayin said to Adonai, “My punishment is greater than I can bear.

Adonai answered him, “Therefore, whoever kills Kayin will receive vengeance sevenfold,” and Adonai put a sign on Kayin, so that no one who found him would kill him.

So Kayin left the presence of Adonai and lived in the land of Nod [wandering], east of ‘Eden.

Kayin had sexual relations with his wife; she conceived and gave birth to Hanokh. Kayin built a city and named the city after his son Hanokh.

If Kayin will be avenged sevenfold, then Lemekh seventy-sevenfold!”

Adam again had sexual relations with his wife, and she gave birth to a son whom she named Shet [granted], “For God has granted me another seed in place of Hevel, since Kayin killed him.”

By trusting, Hevel offered a greater sacrifice than Kayin; because of this, he was attested as righteous, with God giving him this testimony on the ground of his gifts. Through having trusted, he still continues to speak, even though he is dead.

and not be like Kayin, who was from the Evil One and murdered his own brother. Why did he murder him? Because his own actions were evil, and his brother’s were righteous.

Woe to them, in that they have walked the road of Kayin, they have given themselves over for money to the error of Bil‘am, they have been destroyed in the rebellion of Korach.
