If you see among the prisoners a beautiful woman and you desire her, then you may take her as your wife. Bring her to your house, but shave her head and trim her nails. read more.
Remove her prisoner's clothing and let her remain for a month in your house, mourning her parents. After that, you may become her husband and she is to become your wife.

If he has selected her for his son, he is to treat her according to the ordinance for daughters. read more.
