81 And Jehovah spake unto Moses, saying, 2 Take Aaron and his sons with him, and the garments, and the anointing oil, and the bullock of the sin-offering, and the two rams, and the basket of unleavened bread; 3 and assemble thou all the congregation at the door of the tent of meeting. 4 And Moses did as Jehovah commanded him; and the congregation was assembled at the door of the tent of meeting. 5 And Moses said unto the congregation, This is the thing which Jehovah hath 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 skilfully woven band of the ephod, and bound it unto him therewith. 8 And he placed the breastplate upon him: and in the breastplate he put the Urim and the Thummim. 9 And he set the mitre upon his head; and upon the mitre, in front, did he set the golden plate, the holy crown; as Jehovah 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 its vessels, and the laver and its base, 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 clothed them with coats, and girded them with girdles, and bound head-tires upon them; as Jehovah commanded Moses.

(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.
