Genesis 4:11-17

11And now you are cursed from the ground, which has opened its mouth to receive your brother’s [shed] blood from your hand.

12When you cultivate the ground, it shall no longer yield its strength [it will resist producing good crops] for you; you shall be a fugitive and a vagabond [roaming aimlessly] on the earth [in perpetual exile without a home, a degraded outcast].”

13Cain said to the Lord, “My punishment is greater than I can bear.

14Behold, You have driven me out this day from the face of the land; and from Your face (presence) I will be hidden, and I will be a fugitive and an [aimless] vagabond on the earth, and whoever finds me will kill me.”

15And the Lord said to him, “Therefore, whoever kills Cain, a sevenfold vengeance [that is, punishment seven times worse] shall be taken on him [by Me].” And the Lord set a [protective] mark (sign) on Cain, so that no one who found (met) him would kill him.

16So Cain went away from the [manifested] presence of the Lord, and lived in the land of Nod [wandering in exile], east of Eden.

17Cain knew his wife [one of Adam’s descendants] and she conceived and gave birth to Enoch; and Cain built a city and named it Enoch, after the name of his son.
