And for Aaron's sons. The sons of Aaron also are separated not only from the body of the people, but likewise from the Levites; for a peculiar dignity was attached to that family, from whom his successor was afterwards to be taken. [1] And since no single individual was able to perform all their offices, they were distributed amongst them. Hence it was that they were adorned with the coat, the girdle, and the bonnet, "for glory and for beauty." We shall see as to their anointing in the next chapter. Their hands are said be filled, [2] when they are made fit for offering sacrifices, for as long as their hands are unconsecrated (profanae) they are accounted empty, even though they may be very full, since no gift is acceptable to God except in right of the priesthood; consequently their fullness arose from consecration, whereby it came that the oblations duly made had access to God. But we must observe that it is not their father Aaron, but Moses, who sanctifies them, that the power itself, or effect of their sanctification, may rest in God, and may not be transferred to His ministers. Perhaps, too, God would anticipate the calumnies of the ungodly, lest any should afterwards object that Aaron had fraudulently and unjustly extended the honor conferred upon himself alone to his sons also, and thus had unlawfully made it hereditary. He was protected against this reproach by the fact, that the sacerdotal dignity came to them from elsewhere. Besides, by these means the posterity of Moses was more certainly deprived of the hope they may have conceived in consideration of what their father was. Therefore Moses, by inaugurating the children of Aaron, reduced his own to their proper place, lest ally ambition should hereafter tempt them, or lest envy should possess them when they saw themselves put below others.

Footnotes

1 - "Les successeurs de la souveraine sacrificature;" the successors in the sovereign priesthood.

2 - A.V., "consecrate," v. 41. Margin, "fill their hand;" i.e., says Rosenmuller, in loco, "thou shalt deliver them the power of their office. Le Clerc suggests that the phrase is perhaps borrowed from some ancient oriental rite, in which the ensigns of office were put into the hands of those to whom it was entrusted. It appears also, from the following chapter, [15]ver. 24, that all the sacred offerings were placed by Moses in the hands of the priests at their inauguration."

Bonnets - Caps of a simple construction which seem to have been cup-shaped.

For glory and for beauty - See Clarke's note on Exodus 28:2.

And for Aaron's sons thou shalt make coats,.... Of fine linen, of woven work, as in Exodus 39:27, these were different from the broidered coat of the high priest, and the blue robe of the ephod:
and thou shall make for them girdles; linen ones, to gird up their linen coats, which were long, that they might the more expeditiously perform their service; and which is an instruction to all the priests of the Lord, true believers in Christ, to be ready, forward, and diligent in the work of the Lord; and especially to ministers of the word, who, as their doctrines and lives ought to be pure, signified by the priest's linen garment, so they should be girt about with the girdle of truth, and ready upon all occasions to publish and defend it, and to do their work with cheerfulness and faithfulness:
and bonnets shall thou make for them: these were coverings for the head, and of the same kind with the mitre of the high priest, and of the same length, but differed from that in the manner of wrapping the linen, of which they were made; see Gill on Exodus 28:39, and all these were to be made
for glory and beauty: to beautify and adorn them, to make them look like persons of some note and figure, and that they might be respectable among men, and typical, as they all were, of our great and glorious High Priest, the Son of God.

The priest's garments typify the righteousness of Christ. If we appear not before God in that, we shall bear our iniquity, and die. Blessed is he, therefore, that watcheth, and keepeth his garments, Revelation 16:15. And blessed be God that we have a High Priest, appointed of God, and set apart for his work; furnished for his high office by the glory of his Divine majesty, and the beauty of perfect holiness. Happy are we, if by the law spiritually understood, we see that such a High Priest became us; that we cannot draw near to a holy God, or be accepted, but by him. There is no light, no wisdom, no perfection, but from him; no glory, no beauty, but in being like unto him. Let us take encouragement from the power, love, and compassion of our High Priest, to draw near with boldness to the throne of grace, that we may obtain mercy, and find grace to help in time of need.

bonnets--turbans.

The official dress of the sons of Aaron, i.e., of the ordinary priests, was to consist of just the same articles as Aaron's priestly costume (Exodus 28:39). But their body-coat is called weavers' work in Exodus 39:27, and was therefore quite a plain cloth, of white byssus or cotton yarn, though it was whole throughout, ἀῤῥαφος without seam, like the robe of Christ (John 19:23). It was worn close to the body, and, according to Jewish tradition, reached down to the ankles (cf. Josephus, iii. 7, 2). The head-dress of an ordinary priest is called מגבּעה, related to גּביע a basin or cup, and therefore seems to have been in the form of an inverted cup, and to have been a plain white cotton cap. The girdle, according to Exodus 39:29, was of the same material and work for Aaron and his sons. This dress was to be for glory and for beauty to the priests, just as Aaron's dress was to him (Exodus 28:2). The glory consisted in the brilliant white colour, the symbol of holiness; whilst the girdle, which an oriental man puts on when preparing for the duties of an office, contained in the four colours of the sanctuary the indication that they were the officers of Jehovah in His earthly kingdom.
