Exodus 34:2-4

34:2 Be 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. 34:3 No 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.” 34:4 So 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.
