Deuteronomy 22:23-25

New Revised Standard Version, Anglicised Catholic Edition

²³ If there is a young woman, a virgin already engaged to be married, and a man meets her in the town and lies with her, ²⁴ you shall bring both of them to the gate of that town and stone them to death, the young woman because she did not cry for help in the town and the man because he violated his neighbour’s wife. So you shall purge the evil from your midst.

²⁵ But if the man meets the engaged woman in the open country, and the man seizes her and lies with her, then only the man who lay with her shall die.
