In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai.
In the third month after they came out of Egypt. It is computed that the law was given just fifty days after their coming out of Egypt, in remembrance of which the feast of Pentecost was observed the fiftieth day after the passover, and in compliance with which the spirit was poured out upon the apostles, at the feast of Pentecost, fifty days after the death of Christ. Mount Sinai was a place which nature, not art, had made conspicuous, for it was the highest in all that range of mountains. Thus God put contempt upon cities and palaces, setting up his pavilion on the top of a mountain, in a barren desert. It is called Sinai, from the multitude of thorny bushes that over-spread it.
 And Moses went up unto God, and the LORD called unto him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel;
Thus shalt thou say to the house of Jacob, and the children of Israel — The people are called by the names both of Jacob and Israel, to mind them that they who had lately been as low as Jacob when he went to Padan-aram, were now grown as great as God made him when he came from thence, and was called Israel.
 Ye have seen what I did unto the Egyptians, and how I bare you on eagles' wings, and brought you unto myself.
Ye have seen what I did unto the Egyptians, and how I bare you on Eagle's wings — An high expression of the wonderful tenderness God shewed for them. It notes great speed; God not only came upon the wing for their deliverance, but he hastened them out, as it were upon the wing. Also that he did it with great ease, with the strength as well as with the swiftness of an eagle. They that faint not, nor are weary, are said to mount up with wings as eagles, Isaiah 40:31. Especially it notes God's particular care of them, and affection to them. Even Egypt was the nest in which these young ones were first formed as the embryo of a nation: when by the increase of their numbers they grew to some maturity, they were carried out of that nest.
I brought you unto myself — They were brought not only into a state of liberty, but into covenant and communion with God. This, God aims at in all the gracious methods of his providence and grace, to bring us back to himself, from whom we have revolted, and to bring us home to himself, in whom alone we can be happy.
 Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine:
Then ye shall be a peculiar treasure to me — He doth not instance in any one particular favour, but expresseth it in that which was inclusive of all happiness, that he would be to them a God in covenant, and they should be to him a people. Nay you shall be a peculiar treasure: not that God was enriched by them, as a man is by his treasure, but he was pleased to value and esteem them as a man doth his treasure; they were precious in his sight. He took them under his special care and protection, as a treasure that is kept under lock and key. He distinguished them from, and dignified them above all people, as a people devoted to him, and to his service.
 And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.
A kingdom of priests, a holy nation - All the Israelites, if compared with other people, were priests unto God, so near were they to him, so much employed in his immediate service, and such intimate communion they had with him. The tendency of the laws given them was to distinguish them from others, and engage them for God as a holy nation. Thus all believers are, through Christ, made to our God kings and priests, 1 Peter 2:9.
 And Moses came and called for the elders of the people, and laid before their faces all these words which the LORD commanded him.
And Moses laid before their faces all these words — He not only explained to them what God had given him in charge, but put it to their choice, whether they would accept these promises upon these terms or no. His laying it to their faces speaks his laying it to their consciences.
 And all the people answered together, and said, All that the LORD hath spoken we will do. And Moses returned the words of the people unto the LORD.
And they answered together; all that the Lord hath spoken we will do — Thus accepting the Lord to be to them a God, and giving up themselves to be to him a people.
 And the LORD said unto Moses, Go unto the people, and sanctify them to day and to morrow, and let them wash their clothes,
Sanctify the people — As Job before sent and sanctified his sons, Job 1:5. Sanctify them, that is, call them off from their worldly business, and call them to religious exercises, meditation and prayer, that they may receive the law from God's mouth with reverence and devotion. Two things particularly were prescribed as instances of their preparation. 1st, In token of cleansing of themselves from all sinful pollutions, they must wash their clothes. Not that God regards our clothes, but while they were washing their clothes, he would have them think of washing their souls by repentance. It becomes us to appear in clean clothes when we wait upon great men; so clean hearts are required in our attendance on the great God. 2dly, In token of their devoting themselves entirely to religious exercises upon this occasion they must abstain even from lawful enjoyments during these three days, and not come at their wives.
 And be ready against the third day: for the third day the LORD will come down in the sight of all the people upon mount Sinai.
In the sight of all the people — Though they should see no| manner of similitude, yet they should see so much as would convince them, that God was among them of a truth. And so high was the top of Mount Sinai, that it is supposed not only the camp of Israel, but even the countries about might discern some extraordinary appearance of glory upon it.
 And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth the mount shall be surely put to death:
Set bounds — Probably he drew a ditch round at the foot of the hill, which none were to pass upon pain of death. This was to intimate, 1st, That awful reverence which ought to possess the minds of all that worship God. 2dly, The distance which worshippers were kept at under that dispensation, which we ought to take notice of, that we may the more value our privilege under the gospel, having boldness to enter into the holiest by the blood of Jesus, Hebrews 10:19.
 There shall not an hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet soundeth long, they shall come up to the mount.
When the trumpet soundeth long — Then let them take their places at the foot of the mount. Never was so great a congregation called together and preached to at once as this was here. No one man's voice could have reached so many, but the voice of God did.
 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.
Now at length is come that memorable day, in which Israel heard the voice of the Lord God speaking to them out of the midst of the fire and lived, Exodus 19:16. These 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 both the learning senses of seeing and hearing.
