Deuteronomy 21:9

All the elders of that city which is nearest to the slain man shall wash their hands over the heifer whose neck was broken in the valley.

They shall answer and say, “Our hands have not shed this blood, neither have our eyes seen it.

Forgive, LORD, your people Israel, whom you have redeemed, and don’t allow innocent blood among your people Israel.” The blood shall be forgiven them.

When you go out to battle against your enemies, and the LORD your God delivers them into your hands and you carry them away captive,

and see among the captives a beautiful woman, and you are attracted to her, and desire to take her as your wife,

then you shall bring her home to your house. She shall shave her head and trim her nails.
