Exodus 19:20 - Exposition

On the top of the mount . Not, probably, on the highest point of the Sinaitic group, the Jebel Musa, which is out of sight from the plain Er-Rahah, where the Israelites must have been assembled; but on the highest part of the face of Sinai fronting that plain, the Ras Sufsafeh, which would be to the Israelites at the base "the top of the mount." The Lord called Moses up. Perhaps with Aaron, who certainly accompanied him when he next ascended ( Exodus 19:24 ), and who seems to be glanced at in the phrase used at the end of Exodus 19:23
