Exodus 34:2-4

2Be prepared in the morning, and go up in the morning to Mount Sinai, and station yourself for me there on the top of the mountain.

3No one is to come up with you; do not let anyone be seen anywhere on the mountain; not even the flocks or the herds may graze in front of that mountain.”

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