We have here, I. The priests nominated: Aaron and his sons, Exo 28:1. Hitherto every master of a family was priest to his own family, and offered, as he saw cause, upon altars of earth; but now that the families of Israel began to be incorporated into a nation, and a tabernacle of the congregation was to be erected, as a visible centre of their unity, it was requisite there should be a public priesthood instituted. Moses, who had hitherto officiated, and is therefore reckoned among the priests of the Lord (Psa 99:6), had enough to do as their prophet to consult the oracle for them, and as their prince to judge among them; nor was he desirous to engross all the honours to himself, or to entail that of the priesthood, which alone was hereditary, upon his own family, but was very well pleased to see his brother Aaron invested in this office, and his sons after him, while (how great soever he was) his sons after him would be but common Levites. It is an instance of the humility of that great man, and an evidence of his sincere regard for the glory of God, that he had so little regard to the preferment of his own family. Aaron, who had humbly served as a prophet to his younger brother Moses, and did not decline the office (Exo 7:1), is now advanced to be a priest, a high priest to God; for he will exalt those that abase themselves. Nor could any man have taken this honour to himself, but he that was called of God to it, Heb 5:4. God had said of Israel in general that they should be to him a kingdom of priests, Exo 19:6. But because it was requisite that those who ministered at the altar should give themselves wholly to the service, and because that which is every body's work will soon come to be nobody's work, God here chose from among them one to be a family of priests, the father and his four sons; and from Aaron's loins descended all the priests of the Jewish church, of whom we read so often, both in the Old Testament and in the New. A blessed thing it is when real holiness goes, as the ceremonial holiness did, by succession in a family. II. The priests' garments appointed, for glory and beauty, Exo 28:2. Some of the richest materials were to be provided (Exo 28:5), and the best artists employed in the making of them, whose skill God, by a special gift for this purpose, would improve to a very high degree, Exo 28:3. Note, Eminence, even in common arts, is a gift of God, it comes from him, and, as there is occasion, it ought to be used for him. He that teaches the husbandman discretion teaches the tradesman also; both therefore ought to honour God with their gain. Human learning ought particularly to be consecrated to the service of the priesthood, and employed for the adorning of those that minister about holy things. The garments appointed were, 1. Four, which both the high priest and the inferior priests wore, namely, the linen breeches, the linen coat, the linen girdle which fastened it to them, and the bonnet or turban; that which the high priest wore is called a mitre. 2. Four more, which were peculiar to the high priest, namely, the ephod, with the curious girdle of it, the breast-plate of judgment, the long robe with the bells and pomegranates at the bottom of it, and the golden plate on his forehead. These glorious garments were appointed, (1.) That the priests themselves might be reminded of the dignity of their office, and might behave themselves with due decorum. (2.) That the people might thereby be possessed with a holy reverence of that God whose ministers appeared in such grandeur. (3.) That the priests might be types of Christ, who should offer himself without spot to God, and of all Christians, who have the beauty of holiness put upon them, in which they are consecrated to God. Our adorning, now under the gospel, both that of ministers and Christians, is not to be of gold, and pearl, and costly array, but the garments of salvation, and the robe of righteousness, Isa 61:10; Psa 132:9, Psa 132:16. As the filthy garments wherewith Joshua the high priest was clothed signified the iniquity which cleaved to his priesthood, from which care was taken that it should be purged (Zac 3:3, Zac 3:4.), so those holy garments signified the perfect purity that there is in the priesthood of Christ; he is holy, harmless, and undefiled.

Directions are here given concerning the ephod, which was the outmost garment of the high priest. Linen ephods were worn by the inferior priests, Sa1 22:18. Samuel wore one when he was a child (Sa1 2:18), and David when he danced before the ark (Sa2 6:14); but this which the high priest only wore was called a golden ephod, because there was a great deal of gold woven into it. It was a short coat without sleeves, buttoned closely to him, with a curious girdle of the same stuff (Exo 28:6-8); the shoulder-pieces were buttoned together with two precious stones set in gold, one on each shoulder, on which were engraven the names of the children of Israel, Exo 28:9-12. In allusion to this, 1. Christ our high priest appeared to John girt about the breast with a golden girdle, such as was the curious girdle of the ephod, Rev 1:13. Righteousness is the girdle of his loins (Isa 11:6), and should be of ours, Eph 6:14. He is girt with strength for the work of our salvation, and is ready for it. 2. The government is said to be upon his shoulders (Isa 9:6), as Aaron had the names of all Israel upon his shoulders in precious stone. He presents to himself and to his Father a glorious church, Eph 5:27. He has power to support them, interest to recommend them, and it is in him that they are remembered with honour and favour. He bears them before the Lord for a memorial (Exo 28:12), in token of his appearing before God as the representative of all Israel and an advocate for them.

The most considerable of the ornaments of the high priest was this breast-plate, a rich piece of cloth, curiously wrought with gold and purple, etc., two spans long and a span broad, so that, being doubled, it was a span square, Exo 28:16. This was fastened to the ephod with wreathen chains of gold (Exo 28:13, Exo 28:14, Exo 28:22, etc.) both at top and bottom, so that the breast-plate might not be loosed from the ephod, Exo 28:28. The ephod was the garment of service; the breast-plate of judgment was an emblem of honour: these two must by no means be separated. If any man will minister unto the Lord, and do his will, he shall know his doctrine. In this breast-plate, I. The tribes of Israel were recommended to God's favour in twelve precious stones, Exo 28:17-21, Exo 28:19. Some question whether Levi had a precious stone with his name or no. If not, Ephraim and Manasseh were reckoned distinct, as Jacob had said they should be, and the high priest himself, being head of the tribe of Levi, sufficiently represented that tribe. If there was a stone for Levi, as is intimated by this, that they were engraven according to their birth (Exo 28:10), Ephraim and Manasseh were one in Joseph. Aaron was to bear their names for a memorial before the Lord continually, being ordained for men, to represent them in things pertaining to God, herein typifying our great high priest, who always appears in the presence of God for us. 1. Though the people were forbidden to come near, and obliged to keep their distance, yet by the high priest, who had their names on his breast-plate, they entered into the holiest; so believers, even while they are here on this earth, not only enter into the holiest, but by faith are made to sit with Christ in heavenly places, Eph 2:6. 2. The name of each tribe was engraven in a precious stone, to signify how precious, in God's sight, believers are, and how honourable, Isa 43:4. They shall be his in the day he makes up his jewels, Mal 3:17. How small and poor soever the tribe was, it was a precious stone in the breast-plate of the high priest; thus are all the saints dear to Christ, and his delight is in them as the excellent ones of the earth, however men may esteem them as earthen pitchers, Lam 4:2. 3. The high priest had the names of the tribes both on his shoulders and on his breast, intimating both the power and the love with which our Lord Jesus intercedes for those that are his. He not only bears them up upon his heart, as the expression here is (Exo 28:29), carries them in his bosom (Isa 40:11), with the most tender affection. How near should Christ's name be to our hearts, since he is pleased to lay our names so near his! and what a comfort it is to us, in all our addresses to God, that the great high priest of our profession has the names of all his Israel upon his breast before the Lord for a memorial, presenting them to God as the people of his choice, who were to be made accepted in the beloved! Let not any good Christians fear that God has forgotten them, nor question his being mindful of them upon all occasions, when they are not only engraven upon the palms of his hands (Isa 49:16), but engraven upon the heart of the great intercessor. See Sol 8:6. II. The urim and thummim, by which the will of God was made known in doubtful cases, were put in this breast-plate, which is therefore called the breast-plate of judgment, Exo 28:30. Urim and thummim signify light and integrity; many conjectures there are among the learned what they were; we have no reason to think they were any thing that Moses was to make more than what was before ordered, so that either God made them himself, and gave them to Moses, for him to put into the breast-plate, when other things were prepared (Lev 8:8), or no more is meant than a declaration of the further use of what was already ordered to be made. I think the words may be read thus, And thou shalt give, or add, or deliver, to the breast-plate of judgment, the illuminations and perfections, and they shall be upon the heart of Aaron; that is, "He shall be endued with a power of knowing and making known the mind of God in all difficult doubtful cases, relating either to the civil or ecclesiastical state of the nation." Their government was a theocracy: God was their King, the high priest was, under God, their ruler, the urim and thummim were his cabinet-council; probably Moses wrote upon the breast-plate, or wove into it, these words, Urim and Thummim, to signify that the high priest, having on him this breast-plate, and asking counsel of God in any emergency relating to the public, should be directed to take those measures, and give that advice, which God would own. If he was standing before the ark (but without the veil) probably he received instructions from off the mercy-seat, as Moses did (Exo 25:22); thus, it should seem, Phinehas did, Jdg 20:27, Jdg 20:28. If he was at a distance from the ark, as Abiathar was when he enquired of the Lord for David (Sa1 23:6, etc.), then the answer was given either by a voice from heaven or rather by an impulse upon the mind of the high priest, which last is perhaps intimated in that expression, He shall bear the judgment of the children of Israel upon his heart. This oracle was of great use to Israel; Joshua consulted it (Num 27:21), and, it is likely, the judges after him. It was lost in the captivity, and never regained after, though, it should seem, it was expected, Ezr 2:63. But it was a shadow of good things to come, and the substance is Christ. He is our oracle; by him God in these last days makes known himself and his mind to us, Heb 1:2; Joh 1:18. Divine revelation centres in him, and comes to us through him; he is the light, the true light, the faithful witness, the truth itself, and from him we receive the Spirit of truth, who leads into all truth. The joining of the breast-plate to the ephod denotes that his prophetical office was founded in his priesthood; and it was by the merit of his death that he purchased this honour for himself and this favour for us. It was the Lamb that had been slain that was worthy to take the book and to open the seals, Rev 5:9.
