Exodus 34:8-10

8Moses quickly bowed to the ground and worshiped

9and said, “If now I have found favor in your sight, O Lord, let my Lord go among us, for we are a stiff-necked people; pardon our iniquity and our sin, and take us for your inheritance.”

10He said, “See, I am going to make a covenant before all your people. I will do wonders such as have not been done in all the earth, nor in any nation. All the people among whom you live will see the work of the Lord, for it is a fearful thing that I am doing with you.
