16 And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled.   17 And Moses brought forth the people out of the camp to meet with God; and they stood at the nether part of the mount.   18 And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.   19 And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spake, and God answered him by a voice.   20 And the LORD came down upon mount Sinai, on the top of the mount: and the LORD called Moses up to the top of the mount; and Moses went up.   21 And the LORD said unto Moses, Go down, charge the people, lest they break through unto the LORD to gaze, and many of them perish.   22 And let the priests also, which come near to the LORD, sanctify themselves, lest the LORD break forth upon them.   23 And Moses said unto the LORD, The people cannot come up to mount Sinai: for thou chargedst us, saying, Set bounds about the mount, and sanctify it.   24 And the LORD said unto him, Away, get thee down, and thou shalt come up, thou, and Aaron with thee: but let not the priests and the people break through to come up unto the LORD, lest he break forth upon them.   25 So Moses went down unto the people, and spake unto them.

      Now, at length, comes that memorable day, that terrible day of the Lord, that day of judgment, in which Israel heard the voice of the Lord God speaking to them out of the midst of the fire, and lived, Deut. iv. 33. Never was there such a sermon preached, before nor since, as this which was here preached to the church in the wilderness. For,

      I. The preacher was God himself (v. 18): The Lord descended in fire, and (v. 20), The Lord came down upon mount Sinai. The shechinah, or glory of the Lord, appeared in the sight of all the people; he shone forth from mount Paran with ten thousands of his saints (Deut. xxxiii. 2), that is, attended, as the divine Majesty always is, by a multitude of the holy angels, who were both to grace the solemnity and to assist at it. Hence the law is said to be given by the disposition of angels, Acts vii. 53.

      II. The pulpit (or throne rather) was mount Sinai, hung with a thick cloud (v. 16), covered with smoke (v. 18), and made to quake greatly. Now it was that the earth trembled at the presence of the Lord, and the mountains skipped like rams (Ps. cxiv. 4, 7), that Sinai itself, though rough and rocky, melted from before the Lord God of Israel, Judg. v. 5. Now it was that the mountains saw him, and trembled (Hab. iii. 10), and were witnesses against a hard-hearted unmoved people, whom nothing would influence.

      III. The congregation was called together by the sound of a trumpet, exceedingly loud (v. 16), and waxing louder and louder, v. 19. This was done by the ministry of the angels, and we read of trumpets sounded by angels, Rev. viii. 6. It was the sound of the trumpet that made all the people tremble, as those who knew their own guilt, and who had reason to expect that the sound of this trumpet was to them the alarm of war.

      IV. Moses brought the hearers to the place of meeting, v. 17. He that had led them out of the bondage of Egypt now led them to receive the law from God's mouth. Public persons are indeed public blessings when they lay out themselves in their places to promote the public worship of God. Moses, at the head of an assembly worshipping God, was as truly great as Moses at the head of an army in the field.

      V. The introductions to the service were thunders and lightnings, v. 16. These were designed to strike an awe upon the people, and to raise and engage their attention. Were they asleep? The thunders would awaken them. Were they looking another way? The lightnings would engage them to turn their faces towards him that spoke to them. Thunder and lightning have natural causes, but the scripture directs us in a particular manner to take notice of the power of God, and his terror, in them. Thunder is the voice of God, and lightning the fire of God, proper to engage the senses of sight and hearing, those senses by which we receive so much of our information.

      VI. Moses is God's minister, who is spoken to, to command silence, and keep the congregation in order: Moses spoke, v. 19. Some think it was now that he said, I exceedingly fear and quake (Heb. xii. 21); but God stilled his fear by his distinguishing favour to him, in calling him up to the top of the mount (v. 20), by which also he tried his faith and courage. No sooner had Moses got up a little way towards the top of the mount than he was sent down again to keep the people from breaking through to gaze, v. 21. Even the priests or princes, the heads of the houses of their fathers, who officiated for their respective families, and therefore are said to come near to the Lord at other times, must now keep their distance, and conduct themselves with a great deal of caution. Moses pleads that they needed not to have any further orders given them, effectual care being taken already to prevent any intrusions, v. 23. But God, who knew their wilfulness and presumption, and what was now in the hearts of some of them, hastens him down with this in charge, that neither the priests nor the people should offer to force the lines that were set, to come up unto the Lord, but Moses and Aaron on, the men whom God delighted to honour. Observe, 1. What it was that God forbade them--breaking through to gaze; enough was provided to awaken their consciences, but they were not allowed to gratify their vain curiosity. They might see, but not gaze. Some of them, probably, were desirous to see some similitude, that they might know how to make an image of God, which he took care to prevent, for they saw no manner of similitude, Deut. iv. 5. Note, In divine things we must not covet to know more than God would have us know; and he has allowed us as much as is good for us. A desire of forbidden knowledge was the ruin of our first parents. Those that would be wise above what is written, and intrude into those things which they have not seen, need this admonition, that they break not through to gaze. 2. Under what penalty it was forbidden: Lest the Lord break forth upon them (v. 22-24), and many of them perish. Note, (1.) The restraints and warnings of the divine law are all intended for our good, and to keep us out of that danger into which we should otherwise, by our own folly, run ourselves. (2.) It is at our peril if we break the bounds that God has set us, and intrude upon that which he has not allowed us; the Bethshemites and Uzzah paid dearly for their presumption. And, even when we are called to approach God, we must remember that he is in heaven and we upon earth, and therefore it behoves us to exercise reverence and godly fear.

      9 Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel:   10 And they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness.   11 And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink.

      The people having, besides their submission to the ceremony of the sprinkling of blood, declared their well-pleasedness in their God and his law, again and again, God here gives to their representatives some special tokens of his favour to them (for God meets him that rejoices and works righteousness), and admits them nearer to him than they could have expected. Thus, in the New-Testament church, we find the four living creatures, and the four and twenty elders, honoured with places round the throne, being redeemed unto God by the blood of the Lamb which is in the midst of the throne, Rev. iv. 4, 6; v. 8, 9. Observe, 1. They saw the God of Israel (v. 10), that is, they had some glimpse of his glory, in light and fire, though they saw no manner of similitude, and his being no man hath seen nor can see, 1 Tim. vi. 16. They saw the place where the God of Israel stood (so the LXX.), something that came near a similitude, but was not; whatever they saw, it was certainly something of which no image nor picture could be made, and yet enough to satisfy them that God was with them of a truth. Nothing is described but that which was under his feet; for our conceptions of God are all below him, and fall infinitely short of being adequate. They saw not so much as God's feet; but at the bottom of the brightness, and as the footstool or pedestal of it, they saw a most rich and splendid pavement, such as they never saw before nor after, as it had been of sapphires, azure or sky-coloured. The heavens themselves are the pavement of God's palace, and his throne is above the firmament. See how much better wisdom is than the precious onyx or the sapphires, for wisdom was from eternity God's delight (Prov. viii. 30), and lay in his bosom, but the sapphires are the pavement under his feet; there let us put all the wealth of this world, and not in our hearts. 2. Upon the nobles (or elders) of Israel, he laid not his hand, v. 11. Though they were men, the dazzling splendour of his glory did not overwhelm them; but it was so moderated (Job xxvi. 9), and they were so strengthened (Dan. x. 19), that they were able to bear it. Nay, though they were sinful men, and obnoxious to God's justice, yet he did not lay his punishing avenging hand upon them, as they feared he would. When we consider what a consuming fire God is, and what stubble we are before him, we shall have reason to say, in all our approaches to him, It is of the Lord's mercies that we are not consumed. 3. They saw God, and did eat and drink. They had not only their lives preserved, but their vigour, courage, and comfort; it cast no damp upon their joy, but rather increased and elevated it. They feasted upon the sacrifice, before God, in token of their cheerful consent to the covenant now made, their grateful acceptance of the benefits of it, and their communion with God, in pursuance of that covenant. Thus believers eat and drink with Christ at his table, Luke xxii. 30. Blessed are those that shall eat bread in the kingdom of our Father, and drink of the wine new there.
