Exodus 34:8-10

Moses made haste to bow low toward the earth and worship. He said, “If now I have found favor in Your sight, O Lord, I pray, let the Lord go along in our midst, even though the people are so obstinate, and pardon our iniquity and our sin, and take us as Your own possession.” Then God said, “Behold, I am going to make a covenant. Before all your people I will perform miracles which have not been produced in all the earth nor among any of the nations; and all the people among whom you live will see the working of the LORD, for it is a fearful thing that I am going to perform with you.
