Exo 32:18 | JFB | STEP | 15-18. Moses turned, and went down from the mount-- The plain, Er-Raheh, is not visible from the top of Jebel Musa, nor can the mount be descended on the side towards that valley; hence Moses and his companion, who on duty had patiently waited his return in the hollow of the mountain's brow, heard the shouting some time before they actually saw the camp.
