Exodus 21:9 Meaning and Commentary

Exodus 21:9

And if he have betrothed her unto his son
Not caring to betroth and marry her himself, as being more suitable in age for his son than for himself;

he shall deal with her after the manner of daughters;
as if she was his daughter, and give her a dowry: or the son shall treat her after the manner the daughters of Israel are treated when married, by giving her food, raiment, and the duty of marriage, so Jarchi: or after the manner of the daughters of Israel that are virgins, and who are not sold, as Aben Ezra.

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.
