Deuteronomy 22:21; Deuteronomy 22:22

21 she shall be brought to the door of her father’s house and there the men of her town shall stone her to death. She has done an outrageous thing in Israel by being promiscuous while still in her father’s house. You must purge the evil from among you.

22 If a man is found sleeping with another man’s wife, both the man who slept with her and the woman must die. You must purge the evil from Israel.
