Exodus 34:2-4

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

3No one is to come up with you, and do not let anyone be seen throughout the entire mountain. Even the flocks and herds must not graze in front of that mountain.”

4So he carved two tablets of stone like the first. Then Moses rose up early in the morning, went up onto Mount Sinai as Adonai had commanded him, and took in his hand the two tablets of stone.
