81 Yahweh spoke to Moses, saying, 2 “Take Aaron and his sons with him, and the garments, and the anointing oil, and the bull of the sin offering, and the two rams, and the basket of unleavened bread; 3 and assemble all the congregation at the door of the Tent of Meeting.” 4 Moses did as Yahweh commanded him; and the congregation was assembled at the door of the Tent of Meeting. 5 Moses said to the congregation, “This is the thing which Yahweh has commanded to be done.” 6 Moses brought Aaron and his sons, and washed them with water. 7 He put the coat on him, tied the sash on him, clothed him with the robe, put the ephod on him, and he tied the skillfully woven band of the ephod on him, and fastened it to him with it. 8 He placed the breastplate on him; and in the breastplate he put the Urim and the Thummim. 9 He set the turban on his head; and on the turban, in front, he set the golden plate, the holy crown; as Yahweh commanded Moses. 10 Moses took the anointing oil, and anointed the tabernacle and all that was in it, and sanctified them. 11 He sprinkled it on the altar seven times, and anointed the altar and all its vessels, and the basin and its base, to sanctify them. 12 He poured some of the anointing oil on Aaron’s head, and anointed him, to sanctify him. 13 Moses brought Aaron’s sons, and clothed them with coats, and tied sashes on them, and put headbands on them; as Yahweh commanded Moses.

Commentary on Leviticus 8:1-13
(Read Leviticus 8:1-13)
The consecration of Aaron and his sons had been delayed until the tabernacle had been prepared, and the laws of the sacrifices given. Aaron and his sons were washed with water, to signify that they ought to purify themselves from all sinful dispositions, and ever after to keep themselves pure. Christ washes those from their sins in his own blood whom he makes kings and priests to our God, Hebrews 10:22. The anointing of Aaron was to typify the anointing of Christ with the Spirit, which was not given by measure to him. All believers have received the anointing.
