John 8:5

Deuteronomy 22:21-24 NIV
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. 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. If a man happens to meet in a town a virgin pledged to be married and he sleeps with her, you shall take both of them to the gate of that town and stone them to death—the young woman because she was in a town and did not scream for help, and the man because he violated another man’s wife. You must purge the evil from among you.

Ezekiel 16:38-40 NIV
I will sentence you to the punishment of women who commit adultery and who shed blood; I will bring on you the blood vengeance of my wrath and jealous anger. Then I will deliver you into the hands of your lovers, and they will tear down your mounds and destroy your lofty shrines. They will strip you of your clothes and take your fine jewelry and leave you stark naked. They will bring a mob against you, who will stone you and hack you to pieces with their swords.

Leviticus 20:10 NIV
“‘If a man commits adultery with another man’s wife —with the wife of his neighbor—both the adulterer and the adulteress are to be put to death.
