Exodus 34:8-10

And Moses quickly bowed his head toward the earth and worshiped. And he said, “If now I have found favor in your sight, O Lord, please let the Lord go in the midst of us, for it is a stiff-necked people, and pardon our iniquity and our sin, and take us for your inheritance.” And he said, “Behold, I am making a covenant. Before all your people I will do marvels, such as have not been created in all the earth or 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 will do with you.
