in the biblical text to require the hypothesis which assigns the encampment to the plain of er Rahah, and the posting of the people at Sinai to the plain of Sebayeh, but there are various allusions which seem rather to show that such a hypothesis is inadmissible. It is very obvious from Exo 24:17, that the glory of the Lord upon the top of the mountain could be seen from the camp; and from Exo 34:1-3, that the camp, with both the people and their cattle in it, was so immediately in the neighbourhood of Sinai, that the people could easily have ascended the mountain, and the cattle could have grazed upon it. Now this does not apply in the least to the plain of er Rahah, from which not even the top of Jebel Musa can be seen, and where the cattle could not possibly have grazed upon it, but only to the plain of Sebayeh; and therefore proves that the camp in “the desert of Sinai” is not to be sought for in the plain of er Rahah, but in the plain of Sebayeh, which reaches to the foot of Sinai. If it should be objected, on the other hand, that there is not room in this plain for the camp of the whole nation, this objection is quite as applicable to the plain of er Rahah, which is not large enough in itself to take in the entire camp, without including a large portion of the Sheikh valley; and it loses all its force from the fact, that the mountains by which the plain of Sebayeh is bounded, both on the south and east, rise so gently and gradually, that they could be made use of for the camp, and on these sides therefore the space is altogether unlimited, and would allow of the widest dispersion of the people and their flocks.
verses 3-4
Moses had known from the time of his call that Israel would serve God on this mountain (Exo 3:12); and as soon as the people were encamped opposite to it, he went up to God, i.e., up the mountain, to the top of which the cloud had probably withdrawn. There God gave him the necessary instructions for preparing for the covenant: first of all assuring him, that He had brought the Israelites to Himself to make them His own nation, and that He would speak to them from the mountain (Exo 19:4-9); and then ordering him to sanctify the people for this revelation of the Lord (Exo 19:10-15). The promise precedes the demand; for the grace of God always anticipates the wants of man, and does not demand before it has given. Jehovah spoke to Moses “from Mount Horeb.” Moses had probably ascended one of
