Deuteronomy 22:25-29
22:25 But if the man came across the engaged woman in the field and overpowered her and raped her, then only the rapist must die.
22:26 You must not do anything to the young woman – she has done nothing deserving of death. This case is the same as when someone attacks another person and murders him,
22:27 for the man met her in the field and the engaged woman cried out, but there was no one to rescue her.
22:28 Suppose a man comes across a virgin who is not engaged and overpowers and rapes her and they are discovered.
22:29 The man who has raped her must pay her father fifty shekels of silver and she must become his wife because he has violated her; he may never divorce her as long as he lives.
