I. Note the preliminaries of the covenant. The chapter begins with the command to Moses to come up to the mount, with Aaron and other representatives of the people. But he was already there when the command was given, and a difficulty has been found (or, shall we say, made) out of this. The explanation seems reasonable and plain enough, that the long section extending from Exodus xx. 22, and containing the fundamental laws as spoken by God, is closed by our verses 1 and 2, which imply, in the very order to Moses to come up with his companions, that he must first go down to bring them. God dismisses him as a king might end an audience with his minister, by bidding him return with attendants. The singular use of the third person in reference to Moses in the third verse is not explained by supposing another writer; for, whoever wrote it, it would be equally anomalous.
So he comes down from the stern cloud-encircled peak to that great plain where the encampment lay, and all eyes watch his descent. The people gather round him, eager and curious. He recounts 'all the judgments,' the series of laws, which had been lodged in his mind by God, and is answered by the many-voiced shout of too swiftly promised obedience. Glance over the preceding chapters, and you will see how much was covered by 'all that the Lord hath spoken.' Remember that every lip which united in that lightly made vow drew its last breath in the wilderness, because of disobedience, and the burst of homage becomes a sad witness to human weakness and changefulness. The glory of God flashed above them on the barren granite, the awful voice had scarcely died into desert silence, nerves still tingled with excitement, and wills were bowed before Jehovah, manifestly so near. For a moment, the people were ennobled, and obedience seemed easy. They little knew what they were saying in that brief spasm of devotion. It was high-water then, but the tide soon turned, and all the ooze and ugliness, covered now, lay bare and rotting. 'Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.' We may take the lesson to ourselves, and see to it that emotion consolidates into strenuous persistency, and does not die in the very excitement of the vow.
The pledge of obedience was needed before the Covenant could be made, and, as we shall find, was reiterated in the very centre of the ceremonial ratification. For the present, it warranted Moses in preparing for the morrow's ritual. His first step was to prepare a written copy of the laws to which the people had sworn. Here we come across an old, silenced battery from which a heavy fire used to be directed against the historical accuracy of the Pentateuch. Alphabetic writing was of a later date. There could not have been a written code. The statement was a mere attempt of a later age to claim antiquity for comparatively modern legislation. It was no more historical than similar traditions in other countries, Sibylline books, etc. All that is out of court now. Perhaps some other guns will be spiked in due time, that make a great noise just at present. Then comes the erection of a rude altar, surrounded by twelve standing stones, just as on the east of Jordan we may yet see dolmens and menhirs. The altar represents the divine presence; and the encircling stones, Israel gathered around its God. The group is a memorial and a witness to the people,--and a witness against them, if disobedient. Thus two permanent records were prepared, the book and the monument. The one which seemed the more lasting has perished; the more fragile has endured, and will last to the world's end.
II. Note the rite of ratification of the covenant. The ceremonial is complex and significant. We need not stay on the mere picture, impressive and, to our eyes, strange as it is, but rather seek to bring out the meaning of these smoking offerings, and that blood flung on the altar and on the crowd. First came two sorts of sacrifices, offered not by priests, but by selected young men, probably one for each tribe, whose employment in sacrificial functions shows the priestly character of the whole nation, according to the great words of Exodus xix. 6. Burnt-offerings and peace-offerings differed mainly in the use made of the sacrifice, which was wholly consumed by fire in the former, while it was in part eaten by the offerer in the latter. The one symbolised entire consecration; the other, communion with God on the basis of sacrifice. The sin-offering does not appear here, as being of later origin, and the product of the law, which deepened the consciousness of transgression. But these sacrifices, at the threshold of the covenant, receive an expiatory character by the use made of the blood, and witness to the separation between God and man, which renders amity and covenant friendship impossible, without a sacrifice.
