Исход 24:4

These two verses form part of the address of God in Ex 20:22-23:33; for אמר משׁה ואל ("but to Moses He said") cannot be the commencement of a fresh address, which would necessarily require מ אל ויּאמר (cf. Exo 24:12; Exo 19:21; Exo 20:22). The turn given to the expression מ ואל presupposes that God had already spoken to others, or that what had been said before related not to Moses himself, but to other persons. But this cannot be affirmed of the decalogue, which applied to Moses quite as much as to the entire nation (a sufficient refutation of Knobel's assertion, that these verses are a continuation of Exo 19:20-25, and are linked on to the decalogue), but only of the address concerning the mishpatim, or "rights," which commences with Exo 20:22, and, according to Exo 20:22 and Exo 21:1, was intended for the nation, and addressed to it, even though it was through the medium of Moses. What God said to the people as establishing its rights, is here followed by what He said to Moses himself, namely, that he was to go up to Jehovah, along with Aaron, Nadab, Abihu, and seventy elders. At the same time, it is of course implied that Moses, who had ascended the mountain with Aaron alone (Exo 20:21), was first of all to go down again and repeat to the people the "rights" which God had communicated to him, and only when this had been done, to ascend again with the persons named. According to Exo 24:3 and Exo 24:12 (? 9), this is what Moses really did. But Moses alone was to go near to Jehovah: the others were to worship afar off, and the people were not to come up at all.

Moses, as mediator between God and Israel, having received divers laws and ordinances from God privately in the three foregoing chapters, in this chapter, I. Comes down to the people, acquaints them with the laws he had received, and takes their consent to those laws (Exo 24:3), writes the laws, and reads them to the people, who repeat their consent (Exo 24:4-7), and then by sacrifice, and the sprinkling of blood, ratifies the covenant between them and God (Exo 24:5, Exo 24:6, Exo 24:8). II. He returns to God again, to receive further directions. When he was dismissed from his former attendance, he was ordered to attend again (Exo 24:1, Exo 24:2). He did so with seventy of the elders, to whom God made a discovery of his glory (Exo 24:9-11). Moses is ordered up into the mount (Exo 24:12, Exo 24:13); the rest are ordered down to the people (Exo 24:14). The cloud of glory is seen by all the people on the top of mount Sinai (Exo 24:15-17), and Moses is therewith God forty days and forty nights (Exo 24:18).

24:4 Pillars were erected as historical markers, witnessing in history that something momentous had occurred at a certain time at this place. In Hittite treaties, pagan gods were called upon to witness the agreement. In this case, the Hebrews were forbidden to recognize other gods, so pillars served the purpose.
