Genesis 4:13-16

Cain said to GOD, “My punishment is too much. I can’t take it! You’ve thrown me off the land and I can never again face you. I’m a homeless wanderer on Earth and whoever finds me will kill me.” GOD told him, “No. Anyone who kills Cain will pay for it seven times over.” GOD put a mark on Cain to protect him so that no one who met him would kill him. Cain left the presence of GOD and lived in No-Man’s-Land, east of Eden.
