And Moses did as the Lord commanded him, &c.— Aaron and his sons are consecrated. The people are called to the door of the tabernacle to grace the solemnity, and by their prayers to implore the Divine benediction. Moses, according to God's directions, proceeds in the consecration: he first washes them. They who are to preach the efficacy of the blood of Christ must first themselves be washed by it, and shew by their own examples the purity they teach. Aaron is clothed with the beautiful garments and diadem, and anointed with the holy oil, as is also the tabernacle, and all the vessels of the sanctuary. Note: 1. Every believer in Jesus has brighter robes provided for him, even garments of everlasting righteousness, and crowns of glory never-fading. 2. The oil ran down from the high-priest's head to the skirts of his clothing: the gifts and graces of the Holy Ghost, wherewith our great High-Priest was anointed, descend to every member of his body mystical, who have an anointing from the Holy One.
Leviticus 8:4-13
4 And Moses did as the LORD commanded him; and the assembly was gathered together unto the door of the tabernacle of the congregation.
5 And Moses said unto the congregation, This is the thing which the LORD commanded to be done.
6 And Moses brought Aaron and his sons, and washed them with water.
7 And he put upon him the coat, and girded him with the girdle, and clothed him with the robe, and put the ephod upon him, and he girded him with the curious girdle of the ephod, and bound it unto him therewith.
8 And he put the breastplate upon him: also he put in the breastplate the Urim and the Thummim.
9 And he put the mitre upon his head; also upon the mitre, even upon his forefront, did he put the golden plate, the holy crown; as the LORD commanded Moses.
10 And Moses took the anointing oil, and anointed the tabernacle and all that was therein, and sanctified them.
11 And he sprinkled thereof upon the altar seven times, and anointed the altar and all his vessels, both the laver and his foot, to sanctify them.
12 And he poured of the anointing oil upon Aaron's head, and anointed him, to sanctify him.
13 And Moses brought Aaron's sons, and put coats upon them, and girded them with girdles, and put bonnetsa upon them; as the LORD commanded Moses.
