Thematic Bible: The master could marry, or give in marriage

Sheshan had no sons, only daughters. He had an Egyptian servant named Jarha. Sheshan gave his daughter in marriage to his servant Jarha, and she bore him Attai.

When you go to war with your enemies and Jehovah your God hands them over to you, you may take them captive. If you see a beautiful woman among the captives and your heart is set on her, you may marry her. Take her to your home. She should shave her head and cut her nails. read more.
She should no longer wear the clothes she was wearing when you captured her. She may live in your house and mourn the loss of her father and mother for one month. After that you may marry her. Later if you are not happy with the woman you may divorce her. She may go free. But you have slept with her as your wife, so you cannot sell her as a slave or make her into your own slave.

When a man sells his daughter into slavery, she will not go free the way male slaves do. If she does not please the master who has chosen her as a wife, he must let her be bought back by one of her close relatives. He has no right to sell her to foreigners, since he has treated her unfairly. If a man buys a female slave to give to his son, he should treat her like a daughter. read more.
If a man takes a second wife, he must continue to give his first wife the same amount of food and clothing and the same rights that she had before.
