Genesis 4:10-16

The LORD said, “What have you done? The voice of your brother’s [innocent] blood is crying out to Me from the ground [for justice]. [Num 35:33; Deut 21:1-9] And now you are cursed from the ground, which has opened its mouth to receive your brother’s [shed] blood from your hand. [Deut 28:15-20] When 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].” Cain said to the LORD, “My punishment is greater than I can bear. Behold, 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.” And 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. [Gen 4:24] So Cain went away from the [manifested] presence of the LORD, and lived in the land of Nod [wandering in exile], east of Eden.
