Charles Ellicott Commentary Exodus 34:2

"And be ready by the morning, and come up in the morning unto mount Sinai, and present thyself there to me on the top of the mount." — Exodus 34:2 (ASV)

Be ready in the morning. — It was necessary to allow an interval for the hewing of the stones.

In the top of the mount — that is, in the same place as before. (Exodus 24:12; Exodus 24:18.)
