Exodus 34:10

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 whom thou art shall see the work of the LORD, for it is a fearsome thing that I will do with thee.

Exodus 34:10 In-Context

8 And Moses made haste, and bowed his head toward the earth and worshiped.
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 whom thou art shall see the work of the LORD, for it is a fearsome 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.
