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 be set free, as male slaves are.

8 If she is sold to someone who intends to make her his wife, but he doesn't like her, then she is to be sold back to her father; her master cannot sell her to foreigners, because he has treated her unfairly.

9 If a man buys a female slave to give to his son, he is to treat her like a daughter.

10 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.

11 If he does not fulfill these duties to her, he must set her free and not receive any payment.
