Exodus 34:1-3

And the LORD said unto Moses, Hew thee two tables of stone like unto the first: and I will write upon these tables the words that were in the first tables, which thou brakest.

And be ready in the morning, and come up in the morning unto mount Sinai, and present thyself there to me in the top of the mount.

And no man shall come up with thee, neither let any man be seen throughout all the mount; neither let the flocks nor herds feed before that mount.
