Genesis 4:13-15

New Revised Standard Version Catholic Edition

¹³ Cain said to the Lord, “My punishment is greater than I can bear! ¹⁴ Today you have driven me away from the soil, and I shall be hidden from your face; I shall be a fugitive and a wanderer on the earth, and anyone who meets me may kill me.” ¹⁵ Then the Lord said to him, “Not so!^[a] Whoever kills Cain will suffer a sevenfold vengeance.” And the Lord put a mark on Cain, so that no one who came upon him would kill him.
