Exodus 34:2-4

2So be ready by morning, and come up in the morning to Mount Sinai, and present yourself there to Me on the top of the mountain.

3No man is to come up with you, nor let any man be seen anywhere on the mountain; nor let flocks or herds feed in front of that mountain.”

4So Moses cut two tablets of stone like the first ones, and he got up early in the morning and went up on Mount Sinai, as the Lord had commanded him, and took the two tablets of stone in his hand.
