23 “^aIf there is a girl who is a virgin engaged to a man, and another man finds her in the city and lies with her,

Deuteronomy 22:24

24 then you shall bring them both out to the gate of that city, and you shall stone them, and they will die; the girl, because she did not cry out in the city, and the man, because he has violated his neighbor’s wife. Thus you shall purge the evil from among you.
