Genesis 34:9
Ver. 9. And make ye marriages with us,.... There was no objection on their side, it lay on the other; Abraham's servant was charged by him not to take a wife of the Canaanites to his son Isaac; and the same charge was given Jacob by Isaac, Ge 24:3; and therefore Jacob would never agree that his children should marry any of that nation; and marriages with them were afterwards forbidden by the law of Moses, De 7:3;
[and] give your daughters unto us, and take our daughters unto you; for though at present there were no other daughters in Jacob's family, yet there might be hereafter; and the request is, that for the future there might be intermarriages between them, as would be practicable in a course of time.
