Genesis 4:13-15

New Revised Standard Version, Anglicised

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.
