Exodus 34:5-10

Then the LORD descended in the cloud and stood there with Moses as he proclaimed the Name of the LORD. Then the LORD passed by in front of him, and proclaimed, “The LORD, the LORD God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth (faithfulness); keeping mercy and lovingkindness for thousands, forgiving iniquity and transgression and sin; but He will by no means leave the guilty unpunished, visiting (avenging) the iniquity (sin, guilt) of the fathers upon the children and the grandchildren to the third and fourth generations [that is, calling the children to account for the sins of their fathers].” Moses bowed to the earth immediately and worshiped [the Lord]. And he said, “If now I have found favor and lovingkindness in Your sight, O Lord, let the Lord, please, go in our midst, though it is a stiff-necked (stubborn, rebellious) people, and pardon our iniquity and our sin, and take us as Your possession.” Then God said, “Behold, I am going to make a covenant. Before all your people I will do wondrous works (miracles) such as have not been created or produced in all the earth nor among any of the nations; and all the people among whom you live shall see the working of the LORD, for it is a fearful and awesome thing that I am going to do with you.
