Here is, I. The date of this law concerning the day of atonement: it was after the death of the two sons of Aaron (Lev 16:1), which we read, Lev 10:1. 1. Lest Aaron should fear that any remaining guilt of that sin should cleave to his family, or (seeing the priests were so apt to offend) that some after-sin of his other sons should be the ruin of his family, he is directed how to make atonement for his house, that it might keep in with God; for the atonement for it would be the establishment of it, and preserve the entail of the blessing upon it. 2. The priests being warned by the death of Nadab and Abihu to approach to God with reverence and godly fear (without which they came at their peril), directions are here given how the nearest approach might be made, not only without peril, but to unspeakable advantage and comfort, if the directions were observed. When they were cut off for an undue approach, the rest must not say, "Then we will not draw near at all," but, "Then we will do it by rule." They died for their sin, therefore God graciously provides for the rest, that they die not. Thus God's judgments on some should be instructions to others.

II.The design of this law. One intention of it was to preserve a veneration for the most holy place, within the veil, where the shechinah, or divine glory, was pleased to dwell between the cherubim: Speak unto Aaron, that he come not at all times into the holy place, Lev 16:2. Before the veil some of the priests came every day to burn incense upon the golden altar, but within the veil none must ever come but the high priest only, and he but on one day in the year, and with great ceremony and caution. That place where God manifested his special presence must not be made common. If none must come into the presence-chamber of an earthly king uncalled, no, not the queen herself, upon pain of death (Est 4:11), was it not requisite that the same sacred respect should be paid to the Kings of kings? But see what a blessed change is made by the gospel of Christ; all good Christians have now boldness to enter into the holiest, through the veil, every day (Heb 10:19, Heb 10:20); and we come boldly (not as Aaron must, with fear and trembling) to the throne of grace, or mercy-seat, Heb 4:16. While the manifestations of God's presence and grace were sensible, it was requisite that they should thus be confined and upon reserve, because the objects of sense the more familiar they are made the less awful or delightful they become; but now that they are purely spiritual it is otherwise, for the objects of faith the more they are conversed with the more do they manifest of their greatness and goodness: now therefore we are welcome to come at all times into the holy place not made with hands, for we are made to sit together with Christ in heavenly places by faith, Eph 2:6. Then Aaron must not come near at all times, lest he die; we now must come near at all times that we may live: it is distance only that is our death. Then God appeared in the cloud upon the mercy-seat, but now with open face we behold, not in a dark cloud, but in a clear glass, the glory of the Lord, Co2 3:18.

III.The person to whom the work of this day was committed, and that was the high priest only: Thus shall Aaron come into the holy place, Lev 16:3. He was to do all himself upon the day of atonement: only there was a second provided to be his substitute or supporter, in case any thing should befal him, either of sickness or ceremonial uncleanness, that he could not perform the service of the day. All Christians are spiritual priests, but Christ only is the high priest, and he alone it is that makes atonement, nor needed he either assistant or substitute.

IV.The attire of the high priest in this service. He was not to be dressed up in his rich garments that were peculiar to himself: he was not to put on the ephod, with the precious stones in it, but only the linen clothes which he wore in common with the inferior priests, Lev 16:4. That meaner dress did best become him on this day of humiliation; and, being thinner and lighter, he would in it be more expedite for the work or service of the day, which was all to go through his hands. Christ, our high priest, made atonement for sin in our nature; not in the robes of his own peculiar glory, but the linen garments of our mortality, clean indeed, but mean.

That he come not at all times into the holy place - By the holy place we are to understand here what is ordinarily called the Holy of Holies, or most holy place; that place within the veil where the ark of the covenant, etc., were laid up; and where God manifested his presence between the cherubim. In ordinary cases the high priest could enter this place only once in the year, that is, on the day of annual atonement; but in extraordinary cases he might enter more frequently, viz., while in the wilderness, in decamping and encamping, he must enter to take down or adjust the things; and on solemn pressing public occasions, he was obliged to enter in order to consult the Lord: but he never entered without the deepest reverence and due preparation. That it may appear that the grand subject of this chapter, the ordinance of the scape-goat, typified the death and resurrection of Christ, and the atonement thereby made, I beg leave to refer to Heb 9:7-12, and Heb 9:24-26, which I shall here transcribe, because it is a key to the whole of this chapter. "Into the second [tabernacle] went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people. The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing: which was a figure for the time then present, in which were offered both gifts and sacrifices that could not make him that did the service perfect, as pertaining to the conscience; which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation. But Christ being come, a high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; neither by the Blood of Goats and Calves, but by his Own Blood; he entered into the holy place, having obtained eternal redemption for us. For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us: nor yet that he should offer himself often, as the high priest entereth into the holy place every year with the blood of others; (for then must he often have suffered since the foundation of the world); but now once in the end of the world, hath he appeared To Put Away Sin By The Sacrifice Of Himself."

And the Lord said unto Moses, speak unto Aaron thy brother,.... Who was the high priest; and what is here said to him was binding on all high priests in succession from him:

that he come not at all times into the holy place; or "holiness" (p), which was holiness itself, or the most holy place, as distinguished from that which was sometimes called the holy place, where stood the incense altar, the showbread table, and the candlestick, into which Aaron went every day, morning and evening, to do the service there enjoined him; but into the holy of holies here described, as appears by the after description of it, he might not go at all times, or every day, or when he pleased, only once a year, on the day of atonement; though, according to the Jewish writers, he went in four times on that day, first to offer incense, a second time to sprinkle the blood of the bullock, a third time to sprinkle the blood of the goat, and a fourth time to fetch out the censer; and if he entered a fifth time, he was worthy of death (q). Some have observed (r), that this respected Aaron only, and not Moses; that though Aaron might not go in when he pleased, and only at a time fixed, yet Moses might at any time, and consult the Lord upon the mercy seat, see Exo 25:22. Pausanias makes mention of several Heathen temples which were opened but once a year, as the temples of Hades Dindymene, and Eurymone (s), and particularly the temple of Minerva, into which only a priest entered once a year (t); which perhaps was in imitation of the Jewish high priest:

within the vail, before the mercy seat, which is upon the ark; this is a description of the holy place, into which the high priest might not go at any time, or at pleasure; it was within the vail that divided between the holy place, and the most holy, where stood the mercy seat, which was a lid or covering to the ark, at the two ends of which were the cherubim, the seat of the divine Majesty; which was a type of heaven for its holiness, being the habitation of the holy God, Father, Son, and Spirit, and of holy angels, and holy men, and where only holy services are performed; and for its invisibility, where dwells the invisible God, where Christ in our nature is at present unseen by us, and the glories of which are not as yet to be beheld; only faith, hope, and love, enter within the vail, and have to do with unseen objects there; and also for what are in it, as the ark and mercy seat, types of Christ, through whom mercy is communicated in a way of justice, he being the propitiation and the fulfilling end of the law for righteousness. And this caution was given to Aaron:

that he die not; by appearing in the presence of God without his leave and order:

for I will appear in the cloud upon the mercy seat; this one would think should be a reason why he should not die, when he came into the most holy place, because there was the mercy seat, and Jehovah on it: and besides the cloud of incense on it, he went in with, for so many understand by the cloud, the cloud of incense: thus Aben Ezra says, the sense is, that he should not enter but with incense, which would make a cloud, and so the glory not be seen, lest he should die: and Jarchi observes, that the Midrash, or the more mystical and subtle sense is, he shall not go in but with the cloud of incense on the day of atonement; but the more simple meaning, or plain sense of the words is, as the same writer notes, that whereas he did continually appear there in the pillar of cloud; and because his Shechinah or glorious Majesty is revealed there, he is cautioned not to use himself to go in, i.e. at any time; with which agrees the Targum of Jonathan,"for in my cloud the glory of my Shechinah, or divine Majesty, shall be revealed upon the mercy seat.''And this being the case, such a glory being there, though wrapped up in a cloud and thick darkness, it was dangerous to enter but by divine order.

Speak unto Aaron thy brother, that he come not at all times into the holy place within the veil, &c.--Common priests went every day into the part of the sanctuary without the veil to burn incense on the golden altar. But none except the high priest was allowed to enter within the veil, and that only once a year with the greatest care and solemnity. This arrangement was evidently designed to inspire a reverence for the most holy place, and the precaution was necessary at a time when the presence of God was indicated by sensible symbols, the impression of which might have been diminished or lost by daily and familiar observation.

I will appear in the cloud--that is, the smoke of the incense which the high priest burnt on his yearly entrance into the most holy place: and this was the cloud which at that time covered the mercy seat.
