Matthew Henry Commentary Exodus 28:1-5

"And bring thou near 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. And thou shalt make holy garments for Aaron thy brother, for glory and for beauty. And thou shalt speak unto all that are wise-hearted, whom I have filled with the spirit of wisdom, that they make Aaron`s garments to sanctify him, that he may minister unto me in the priest`s office. And these are the garments which they shall make: a breastplate, and an ephod, and a robe, and a coat of checker work, a mitre, and a girdle: and they shall make holy garments for Aaron thy brother, and his sons, that he may minister unto me in the priest`s office. And they shall take the gold, and the blue, and the purple, and the scarlet, and the fine linen." — Exodus 28:1-5 (ASV)

Previously, the heads of families were the priests and offered sacrifices; but now this office was confined to the family of Aaron only, and so it continued until the gospel dispensation.

The holy garments not only distinguished the priests from the people but were emblems of that holy conduct which should always be the glory and beauty, the mark of the ministers of religion. Without such conduct, their persons and ministrations will be held in contempt. These garments also typified the glory of the Divine majesty and the beauty of complete holiness, which made Jesus Christ the great High Priest.

But our adornment under the gospel is not to be of gold and costly attire, but rather the garments of salvation, the robe of righteousness.
