Exodus 34:10-16

10And he said, "Behold, I am making a covenant. Before all your people I will do marvels, such as have not been created in all the earth or in any nation. And all the people among whom you are shall see the work of the Lord, for it is an awesome thing that I will do with you.

11"Observe what I command you this day. Behold, I will drive out before you the Amorites, the Canaanites, the Hittites, the Perizzites, the Hivites, and the Jebusites.

12Take care, lest you make a covenant with the inhabitants of the land to which you go, lest it become a snare in your midst.

13You shall tear down their altars and break their pillars and cut down their Asherim

14(for you shall worship no other god, for the Lord, whose name is Jealous, is a jealous God),

15lest you make a covenant with the inhabitants of the land, and when they whore after their gods and sacrifice to their gods and you are invited, you eat of his sacrifice,

16and you take of their daughters for your sons, and their daughters whore after their gods and make your sons whore after their gods.
