The pardon of Israel's sin in worshipping the calf was now to pass the seals; and God, by this declaration, would let them know that he pardoned ex mero motu - merely out of…

34:5-9 Moses experienced God’s presence in a revelation of the name, or character, of God. As God had promised (33:19), he showed Moses the glory of his goodness. 34:5-6 Yahweh: Here God is emphasizing his personal name.
