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 "Whenever a man sells his daughter into slavery, she will not go free the way male slaves do.

8 If she doesn't 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.

9 But if he has chosen her for his son, he must treat her like a daughter.

10 If that son marries another woman, he must not deprive the first wife of food, clothes, or sex.

11 If he doesn't give her these three things, she can go free, without paying any money for her freedom.
