Exodus 21:9 In-Context

7 "If a man sells his daughter as a slave, she is not to go free like the men-slaves.
8 If her master married her but decides she no longer pleases him, then he is to allow her to be redeemed. He is not allowed to sell her to a foreign people, because he has treated her unfairly.
9 If he has her marry his son, then he is to treat her like a daughter.
10 If he marries another wife, he is not to reduce her food, clothing or marital rights.
11 If he fails to provide her with these three things, she is to be given her freedom without having to pay anything.
