Exodus 34:10-16

10And He said: “Behold, I make a covenant. Before all your people I will do marvels such as have not been done in all the earth, nor 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.

11Observe what I command you this day. Behold, I am driving out from before you the Amorite and the Canaanite and the Hittite and the Perizzite and the Hivite and the Jebusite.

12Take heed to yourself, lest you make a covenant with the inhabitants of the land where you are going, lest it be a snare in your midst.

13But you shall destroy their altars, break their sacred pillars, and cut down their wooden images

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 they play the harlot with their gods and make sacrifice to their gods, and one of them invites you and you eat of his sacrifice,

16and you take of his daughters for your sons, and his daughters play the harlot with their gods and make your sons play the harlot with their gods.
