Exodus 34:16 Meaning and Commentary

Exodus 34:16

And thou take of their daughters unto thy sons
That is, marry them to them, which explains what is meant by making a covenant with them, entering into such a near relation, and joining families, and thus intermixing with one another;

and their daughters go a whoring after their gods;
the worship of whom they have been trained up in from their infancy, and therefore hanker after them, and commit whoredom in a spiritual sense with them;

and make thy sons go a whoring after their gods;
by the means of tempting and drawing them into idolatrous practices, as the wives of Solomon were a snare to him.

15 lest at any time thou make a covenant with the dwellers on the land, and they go a whoring after their gods, and sacrifice to their gods, and they call thee, and thou shouldest eat of their feasts,
16 and thou shouldest take of their daughters to thy sons, and thou shouldest give of thy daughters to their sons; and thy daughters should go a whoring after their gods, and thy sons should go a whoring after their gods.
17 And thou shalt not make to thyself molten gods.
18 And thou shalt keep the feast of unleavened bread: seven days shalt thou eat unleavened bread, as I have charged thee, at the season in the month of new ; for in the month of new thou camest out from Egypt.
