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 When a man sells his daughter as a slave, she shouldn't be set free in the same way as male slaves are set free.

8 If she doesn't please her master who chose her for himself, then her master must let her be bought back by her family. He has no right to sell her to a foreign people since he has treated her unfairly.

9 If he assigns her to his son, he must give her the rights of a daughter.

10 If he takes another woman for himself, he may not reduce her food, clothing, or marital rights.

11 If he doesn't do these three things for her, she will go free without any payment, for no money.
