Exodus 34:1-3

Now the Lord said to Moses, “Cut out for yourself two stone tablets like the former ones, and I will write on the tablets the words that were on the former tablets which you smashed.

So 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.

And no one is to come up with you, nor let anyone be seen anywhere on the mountain; even the flocks and the herds are not to graze in front of that mountain.”
