Exodus 34:1-3

Then the LORD told Moses, “Chisel out two stone tablets like the first ones. I will write on them the same words that were on the tablets you smashed. Be ready in the morning to climb up Mount Sinai and present yourself to me on the top of the mountain. No one else may come with you. In fact, no one is to appear anywhere on the mountain. Do not even let the flocks or herds graze near the mountain.”
