Exodus 34:5

2 And be ready by the morning, and come up on Mount Sinai, and come before me there in the morning, on the top of the mountain.

3 No one is to come up with you, and let no man be seen anywhere on the mountain; let no flocks or herds come near to get their food at its foot.

4 So Moses got two stones cut like the first; and early in the morning he went up Mount Sinai, as the Lord had said, with the two stones in his hand.

5 And the Lord came down in the cloud and took his place by the side of Moses, and Moses gave worship to the name of the Lord.

6 And the Lord went past before his eyes, saying, The Lord, the Lord, a God full of pity and grace, slow to wrath and great in mercy and faith;

7 Having mercy on thousands, overlooking evil and wrongdoing and sin; he will not let wrongdoers go free, but will send punishment on children for the sins of their fathers, and on their children's children to the third and fourth generation.

8 Then Moses quickly went down on his face in worship.
