Exodus 34:10-16

10And he said, Behold, I make a covenant: before all thy people I will do wonders, such as have not been done in all the earth, nor in any nation: and all the people among which thou art shall see the work of the LORD: for it is a terrible thing that I will do with thee. 11Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite. 12Take heed to thyself, lest thou make a covenant with the inhabitants of the land where thou goest, lest it be for a snare in the midst of thee: 13But ye shall destroy their altars, break their images, and cut down their groves:1 14For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God: 15Lest thou make a covenant with the inhabitants of the land, and they go astray after their gods, and sacrifice to their gods, and one call thee, and thou eat of his sacrifice; 16And thou take of their daughters to thy sons, and their daughters go astray after their gods, and make thy sons go astray after their gods.
