Deuteronomy 22:23-25

New Catholic Bible

²³ If a man encounters a young woman who is betrothed to another man and he sleeps with her, ²⁴ you shall take both of them to the city gate and stone them to death, the young woman because she was inside of the city and did not cry out, and the man because he violated his neighbor’s wife. You must purge the evil from among you.

²⁵ But if a man encounters a young woman betrothed to another man in the countryside and he overcomes her and has sex with her, then only the man who has done this is to die.
