Exodus 34:13

He said, “Behold, I make a covenant: before all your people I will do marvels, such as have not been worked 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 do with you.

Observe that which I command you today. Behold, I will drive out before you the Amorite, the Canaanite, the Hittite, the Perizzite, the Hivite, and the Jebusite.

Be careful, lest you make a covenant with the inhabitants of the land where you are going, lest it be for a snare among you;

for you shall worship no other god; for the LORD, whose name is Jealous, is a jealous God.

“Don’t make a covenant with the inhabitants of the land, lest they play the prostitute after their gods, and sacrifice to their gods, and one call you and you eat of his sacrifice;

and you take of their daughters to your sons, and their daughters play the prostitute after their gods, and make your sons play the prostitute after their gods.
