81 The Lord said to Moses, 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 And Moses did as the Lord commanded him; and the congregation was assembled at the door of the tent of meeting. 5 And Moses said to the congregation, "This is the thing which the Lord has commanded to be done." 6 And Moses brought Aaron and his sons, and washed them with water. 7 And he put on him the coat, and girded him with the girdle, and clothed him with the robe, and put the ephod upon him, and girded him with the skilfully woven band of the ephod, binding it to him therewith. 8 And he placed the breastpiece on him, and in the breastpiece he put the Urim and the Thummim. 9 And he set the turban upon his head, and on the turban, in front, he set the golden plate, the holy crown, as the Lord commanded Moses. 10 Then Moses took the anointing oil, and anointed the tabernacle and all that was in it, and consecrated them. 11 And he sprinkled some of it on the altar seven times, and anointed the altar and all its utensils, and the laver and its base, to consecrate them. 12 And he poured some of the anointing oil on Aaron's head, and anointed him, to consecrate him. 13 And Moses brought Aaron's sons, and clothed them with coats, and girded them with girdles, and bound caps on them, as the Lord commanded Moses.

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.
