And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
Aaron and his sons — Hitherto every master of a family was priest to his own family. But now 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 publick priesthood instituted. Moses, who had hitherto officiated, and is therefore reckoned among the priests of the Lord, Psalms 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 ingross 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 with 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 to the glory of God, that he had so little regard to the preferment of his own family. Aaron, that had humbly served as a prophet to his younger brother Moses, and did not decline the office, is now advanced to be a priest to God. God had said to Israel in general, that they should be to him a kingdom of priests; but because it was requisite that those who ministered at the altar should give themselves wholly to the service, 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, whom we read of both in the Old Testament and in the New.
 And thou shalt make holy garments for Aaron thy brother for glory and for beauty.
The priests garments were made for glory and beauty - Some of the richest materials were to be provided, and the belt artists employed in making them, whose skill God, by a special gift, would improve to a very high degree. Eminency, even in common arts, is a gift of God; it comes from him, and, ought to be used for him. The garments appointed were, (1.) Four, which both the high-priest and the inferior priests wore, viz. The linen breeches, the linen coat, the linen girdle which fastened it to them, and the bonnet; that which the high-priest wore is called a mitre. (2.) Four more which were peculiar to the high-priest, the ephod, with the curious girdle of it, the breast-plate of judgment, the long robe, and the golden plate on his forehead. These glorious garments, were appointed, 1. That the priests themselves might be minded of the dignity of their office. 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, and of all Christians who have the beauty of holiness put upon them.
 And they shall make the ephod of gold, of blue, and of purple, of scarlet, and fine twined linen, with cunning work.
The ephod, was the outmost garment of the high-priest; linen ephods were worn by the inferior priests, but this, which the high-priest 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 close to him with a curious girdle of the same stuff. The shoulder pieces were buttoned together with two precious stones set in gold, one on each shoulder. In allusion to this, Christ our high priest appeared to John, girt about the paps with a golden girdle, such as was the curious girdle of the ephod, Ephesians 5:27. He bears them before the Lord for a memorial, in token of his appearing before God as the representative of all Israel, and an advocate for them.
 With the work of an engraver in stone, like the engravings of a signet, shalt thou engrave the two stones with the names of the children of Israel: thou shalt make them to be set in ouches of gold.
Ouches — Hollow places, such as are made in gold rings, to receive and hold the precious stones.
 And thou shalt make the breastplate of judgment with cunning work; after the work of the ephod thou shalt make it; of gold, of blue, and of purple, and of scarlet, and of fine twined linen, shalt thou make it.
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, two spans long, and a span broad; so that, being doubled, it was a span square. In this breast-plate, the tribes of Israel were recommended to God's favour in twelve precious stones. Some question whether Levi had a precious stone with his name on 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. 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. The name of each tribe was engraven in a precious stone, to signify how precious, in God's sight, believers are, and how honourable, Isaiah 43:4. The high priest had the names of the tribes both on his shoulders and on his breast, noting both the power and the love with which our Lord Jesus interceeds for us. How near should Christ's name lie to our hearts, since he is pleased to lay our names so near his? And what a comfort is it 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?
 And thou shalt put in the breastplate of judgment the Urim and the Thummim; and they shall be upon Aaron's heart, when he goeth in before the LORD: and Aaron shall bear the judgment of the children of Israel upon his heart before the LORD continually.
The Urim and Thummim — By which the will of God was made known in doubtful cases, was put in this breast-plate, which is therefore called the breast-plate of judgment. 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; or, no more is meant but a declaration of the farther use of what was already ordered to be made. The words may be read thus, And thou shalt give, or add, 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 cases relating either to the civil or ecclesiastical state. Their government was a theocracy; God was their king, the high priest was, under God, their ruler, this 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 council of God in any emergency, should be directed to those measures, which God would own. If he were standing before the ark, probably he received instructions from off the mercy-seat, as Moses did, Revelation 5:9.
The judgment — The breast-plate of judgment: That breast-plate which declared the judgment or mind of God to the Israelites.
 And thou shalt make the robe of the ephod all of blue.
The robe of the ephod — This was next under the ephod, and reached down to the knees, without sleeves, and was put on over their head, having holes on the sides to put the arms through, or, as Maimonides describes it, was not sewn together on the sides at all. The hole on the top through which the head was put was carefully bound about, that it might not tear in the putting on. The bells gave notice to the people in the outer court, when he went into the holy place to burn incense, that they might then apply themselves to their devotions at the same time, Luke 1:10, in token of their concurrence with him, and their hopes of the ascent of their prayers to God in the virtue of the incense he offered. Aaron must come near to minister in the garments that were appointed him, that he die not. 'Tis at his peril if he attend otherwise than according to the institution.
 And there shall be an hole in the top of it, in the midst thereof: it shall have a binding of woven work round about the hole of it, as it were the hole of an habergeon, that it be not rent.
An habergeon — A coat of armour.
 And beneath upon the hem of it thou shalt make pomegranates of blue, and of purple, and of scarlet, round about the hem thereof; and bells of gold between them round about:
Pomegranates — The figures of Pomegranates, but flat and embroidered.
 And thou shalt make a plate of pure gold, and grave upon it, like the engravings of a signet, HOLINESS TO THE LORD.
On the golden plate fixed upon Aaron's forehead, like an half coronet, reaching, as the Jews say, from ear to ear, must be engraven, Holiness to the Lord - Aaron must hereby be minded, that God is holy, and that his priests must be holy. The high priest must be consecrated to God, and so must all his ministrations. All that attend in God's house must have holiness to the Lord engraven upon their foreheads, that is, they must he holy, devoted to the Lord, and designing his glory in all they do. This must appear in their forehead, in an open profession of their relation to God, as those that are not ashamed to own it, and in a conversation answerable to it. It must likewise be engraven like the engravings of a signet, so deep, so durable; not painted, so as it may he washed off, but sincere and lasting.
 And it shall be upon Aaron's forehead, that Aaron may bear the iniquity of the holy things, which the children of Israel shall hallow in all their holy gifts; and it shall be always upon his forehead, that they may be accepted before the LORD.
Aaron must have this upon his forehead, that he may bear the iniquity of the holy things, and that they may be accepted before the Lord - Herein he was a type of Christ, the great Mediator between God and man. Thro' him what is amiss in our services is pardoned: even this would be our ruin, if God should enter into judgment with us: but Christ our high priest bears this iniquity; bears it for us, so as to bear it from us. Thro' him likewise what is good is accepted; our persons, our performances are pleasing to God upon the account of Christ's intercession, and not otherwise. His being holiness to the Lord, recommends all those to the divine favour that believe in him. Having such a high priest, we come boldly to the throne of grace.
 And thou shalt embroider the coat of fine linen, and thou shalt make the mitre of fine linen, and thou shalt make the girdle of needlework.
The embroidered coat of fine linen - Was the innermost of the priestly garments, it reached to the feet, and the sleeves to the wrists, and was bound to the body with a girdle or sash of needlework. The mitre or diadem was of linen, such as kings anciently wore in the east, typifying the kingly office of Christ.
 And they shall be upon Aaron, and upon his sons, when they come in unto the tabernacle of the congregation, or when they come near unto the altar to minister in the holy place; that they bear not iniquity, and die: it shall be a statute for ever unto him and his seed after him.
It shall be a statute for ever — That is, It is to continue as long as the priesthood continues. And it is to have its perpetuity in the substance, of which these things were the shadows.
