Exodus 34:10

10 He said: I hereby make a covenant. Before all your people I will perform marvels, such as have not been performed in all the earth or in any nation; and all the people among whom you live shall see the work of the Lord; for it is an awesome thing that I will do with you.

Exodus 34:10 In-Context

8 And Moses quickly bowed his head toward the earth, and worshiped.
9 He said, "If now I have found favor in your sight, O Lord, I pray, let the Lord go with us. Although this is a stiff-necked people, pardon our iniquity and our sin, and take us for your inheritance."
10 He said: I hereby make a covenant. Before all your people I will perform marvels, such as have not been performed in all the earth or in any nation; and all the people among whom you live shall see the work of the Lord; for it is an awesome thing that I will do with you.
11 Observe what I command you today. See, I will drive out before you the Amorites, the Canaanites, the Hittites, the Perizzites, the Hivites, and the Jebusites.
12 Take care not to make a covenant with the inhabitants of the land to which you are going, or it will become a snare among you.
