EXPOSITION
The further warning to the people and the priests. It is very remarkable that, after all the directions given (Exodus 19:10-13), and all the pains taken by Moses and the Israelites themselves (Exodus 19:14, Exodus 19:15, Exodus 19:23), God should still have thought it necessary to interpose with a fresh warning, and to send Moses back from the top of the mount to the bottom, in order to communicate the renewed warning to the people. We can only suppose that, in spite of the instructions previously given and the precautions taken, there were those among the people who were prepared to "break through" the fence, and invade the mount, and who would have done so, to their own destruction (Exodus 19:21), but for this second warning. The special mention of the "priests" (Exodus 19:22, Exodus 19:24) raises the suspicion, that this proud and rebellious spirit was particularly developed among them. Accustomed to the exercise of sacred functions, they may have been inclined to regard their own purity as equal to that of Moses and Aaron; and they may even have resented their exclusion from a sacred spot to which the two sons of Amram were admitted. Apparently, they had conceived that the injunction to go through the recognised ceremonies of purification (Exodus 19:10) did not apply to them, and had neglected to do so, on which account a special command had.to be issued, addressed to them only (Exodus 19:22).
