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.

8 If she doesn't please her master, who has married her to himself, then he shall let her be redeemed. He shall have no right to sell her to a foreign people, seeing he has dealt deceitfully with her.

9 If he marries her to his son, he shall deal with her after the manner of daughters.

10 If he takes another wife to himself, he shall not diminish her food, her clothing, and her marital rights.
