Genesis 4:8-15

8Cain talked with Abel his brother [about what God had said]. And when they were [alone, working] in the field, Cain attacked Abel his brother and killed him.

9Then the Lord said to Cain, “Where is Abel your brother?” And he [lied and] said, “I do not know. Am I my brother’s keeper?”

10The Lord said, “What have you done? The voice of your brother’s [innocent] blood is crying out to Me from the ground [for justice].

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.
