Deuteronomy 7:3-5

3 Do not marry any of them, and do not let your children marry any of them,

4 because then they would lead your children away from the LORD to worship other gods. If that happens, the LORD will be angry with you and destroy you at once.

5 So then, tear down their altars, break their sacred stone pillars in pieces, cut down their symbols of the goddess Asherah, and burn their idols.
