Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel:

Then Moses and Aaron, Nadab and Abiu, and seventy of the ancients of Israel went up:

And Moses goeth up, Aaron also, Nadab and Abihu, and seventy of the elders of Israel,

Then Moses and Aaron, Nadab, and Abihu, and seventy of the chiefs of Israel went up:

And Moses and Aaron, Nadab and Abihu, and seventy of the elders of Israel ascended.

Ascendit autem Moses, et Aharon, Nadab et Abihu, et septuaginta e senioribus Israel.

Then went up Moses and Aaron, Nadab and Abihu. Thus it is that I connect the history: Moses, having finished reading the Law, and having sprinkled the blood, took with him the companions pointed out to him by God, and having left the people, went with these some way up the mountain. I have thought it well slightly to touch upon this, because some translators render the verb improperly in the pluperfect tense, as if he and the elders had already before been separated from the people; but this is very absurd, for it was necessary for him to remain in the plain, in order to address the people. There the glory of God was beheld more closely by the elders, that they might afterwards relate to the people what they had seen, and that thus the thing, being proved by competent witnesses, might obtain undoubted credit. For this reason he says, that "they saw the God of Israel," not in all His reality and greatness, but in accordance with the dispensation which He thought best, and which he accommodated to the capacity of man. The form of God is indeed nowhere described, but the pediment (basis) on which He stood was like a work of sapphire. [1] The word lvnt, libnath, some translate stone, others whiteness, others brick. Whichever sense it is preferred to take it in, but little affects the main point in the matter; for the color of a sapphire was presented to them, to elevate their minds by its brightness above the world; and therefore it is immediately added, that its appearance was as of the clear and serene sky. By this symbol they were reminded that the glory of God is above all heavens; and since in His very footstool there is such exquisite and surpassing beauty, something still more sublime must be thought of Himself, and such as would ravish all our senses with admiration. Thus the throne of God was shewn to Ezekiel "as the appearance of a sapphire-stone." (Ezekiel 1:26; 10:1.) Finally, on the footstool Infinite Majesty appeared, such as to strike the elders with astonishment, so that they might humble themselves with greater reverence before the incomprehensible glory of God.

1 - Ainsworth, "A work of sapphire-brick. Heb., brick of sapphire: whereby is meant sapphire-stone, hewed like brick, wherewith the place under Him was paved. So also the Greek translateth it. Or, it may be Englished, of whiteness of sapphire, i.e., of white sapphire-stone: for brick hath the name in Hebrew of whiteness. The Chaldee translateth, under the throne of his glory was, as it were, a work of precious, stone." "The Hebrews, (says Willet, in loco,) whom Lyranus and Lippoman follow, -- in that the pavement or brick-work was like sapphire, -- understand the happy change which was now made for Israel: their servitude in making of brick was turned into glorious liberty, as if a floor should be paved with sapphire instead of brick!"

It would appear that Moses, Aaron with his two sons, and seventy of the elders Exodus 19:7 went a short distance up the mountain to eat the meal of the covenant (compare Genesis 31:43-47), which must have consisted of the flesh of the peace offerings Exodus 24:5. Joshua accompanied Moses as his servant Exodus 24:13.

Then went up Moses and Aaron, Nadab and Abihu,.... After the above things were done, the words of the Lord were told the people, and the book of the covenant read unto them, to which they agreed, sacrifices were offered, and the blood of them sprinkled on the altar, and on the people. The Samaritan version adds to these, Eleazar and Ithamar, the two younger sons of Aaron:
and seventy of the elders of Israel, who were called up to the mountain to the Lord, Exodus 24:1.

The elders saw the God of Israel; they had some glimpse of his glory, though whatever they saw, it was something of which no image or picture could be made, yet enough to satisfy them that God was with them of a truth. Nothing is described but what was under his feet. The sapphires are the pavement under his feet; let us put all the wealth of this world under our feet, and not in our hearts. Thus the believer sees in the face of Jesus Christ, far clearer discoveries of the glorious justice and holiness of God, than ever he saw under terrifying convictions; and through the Saviour, holds communion with a holy God.

Then went up Moses, and Aaron--in obedience to a command given (Exodus 24:1-2; also Exodus 19:24), previous to the religious engagement of the people, now described.
Nadab, and Abihu--the two oldest sons of Aaron [Exodus 6:23].
seventy of the elders--a select number; what was the principle of selection is not said; but they were the chief representatives, the most conspicuous for official rank and station, as well as for their probity and weight of character in their respective tribes.

Through their consecration with the blood of the covenant, the Israelites were qualified to ascend the mountain, and there behold the God of Israel and celebrate the covenant meal; of course, not the whole of the people, for that would have been impracticable on physical grounds, but the nation in the persons of its representatives, viz., the seventy elders, with Aaron and his two eldest sons. The fact that the latter were summoned along with the elders had reference to their future election to the priesthood, the bearers of which were to occupy the position of mediators between Jehovah and the nation, an office for which this was a preparation. The reason for choosing seventy out of the whole body of elders (Exodus 24:3) is to be found in the historical and symbolical significance of this number. "They saw the God of Israel." This title is very appropriately given to Jehovah here, because He, the God of the fathers, had become in truth the God of Israel through the covenant just made. We must not go beyond the limits drawn in Exodus 33:20-23 in our conceptions of what constituted the sight (חזה Exodus 24:11) of God; at the same time we must regard it as a vision of God in some form of manifestation which rendered the divine nature discernible to the human eye. Nothing is said as to the form in which God manifested Himself. This silence, however, is not intended "to indicate the imperfection of their sight of God," as Baumgarten affirms, nor is it to be explained, as Hoffmann supposes, on the ground that "what they saw differed from what the people had constantly before their eyes simply in this respect, that after they had entered the darkness, which enveloped the mountain that burned as it were with fire at its summit, the fiery sign separated from the cloud, and assumed a shape, beneath which it was bright and clear, as an image of untroubled bliss." The words are evidently intended to affirm something more than, that they saw the fiery form in which God manifested Himself to the people, and that whilst the fire was ordinarily enveloped in a cloud, they saw it upon the mountain without the cloud. For, since Moses saw the form (תּמוּנה) of Jehovah (Numbers 12:8), we may fairly conclude, notwithstanding the fact that, according to Exodus 24:2, the representatives of the nation were not to draw near to Jehovah, and without any danger of contradicting Deuteronomy 4:12 and Deuteronomy 4:15, that they also saw a form of God. Only this form is not described, in order that no encouragement might be given to the inclination of the people to make likenesses of Jehovah. Thus we find that Isaiah gives no description of the form in which he saw the Lord sitting upon a high and lofty throne (Isaiah 6:1). Ezekiel is the first to describe the form of Jehovah which he saw in the vision, "as the appearance of a man" (Ezekiel 1:26; compare Daniel 7:9 and Daniel 7:13). "And there was under His feet as it were work of clear sapphire (לבנת, from לבנה whiteness, clearness, not from לבנה a brick),
(Note: This is the derivation adopted by the English translators in their rendering "paved work." - Tr.)
and as the material (עצם body, substance) of heaven in brilliancy," - to indicate that the God of Israel was enthroned above the heaven in super-terrestrial glory and undisturbed blessedness. And God was willing that His people should share in this blessedness, for "He laid not His hand upon the nobles of Israel," i.e., did not attack them. "They saw God, and did eat and drink," i.e., they celebrated thus near to Him the sacrificial meal of the peace-offerings, which had been sacrificed at the conclusion of the covenant, and received in this covenant meal a foretaste of the precious and glorious gifts with which God would endow and refresh His redeemed people in His kingdom. As the promise in Exodus 19:5-6, with which God opened the way for the covenant at Sinai, set clearly before the nation that had been rescued from Egypt the ultimate goal of its divine calling; so this termination of the ceremony was intended to give to the nation, in the persons of its representatives, a tangible pledge of the glory of the goal that was set before it. The sight of the God of Israel was a foretaste of the blessedness of the sight of God in eternity, and the covenant meal upon the mountain before the face of God was a type of the marriage supper of the Lamb, to which the Lord will call, and at which He will present His perfected Church in the day of the full revelation of His glory (Revelation 19:7-9).
