Exodus 34:12

9 And he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us; for it [is] a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.

10 And he said, Behold, I make a covenant: before all thy people I will do marvels, 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.

11 Observe 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.

12 Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee:

13 But ye shall destroy their altars, break their images, and cut down their groves:

14 For thou shalt worship no other god: for the LORD, whose name [is] Jealous, [is] a jealous God:

15 Lest thou make a covenant with the inhabitants of the land, and they go a whoring after their gods, and do sacrifice unto their gods, and [one] call thee, and thou eat of his sacrifice;
