81 And the Lord spoke to Moses, saying: 2 "Take Aaron and his sons with him, and the garments, the anointing oil, a bull as the sin offering, two rams, and a basket of unleavened bread; 3 and gather all the congregation together at the door of the tabernacle of meeting." 4 So Moses did as the Lord commanded him. And the congregation was gathered together at the door of the tabernacle of meeting. 5 And Moses said to the congregation, "This is what the Lord commanded to be done." 6 Then Moses brought Aaron and his sons and washed them with water. 7 And he put the tunic on him, girded him with the sash, clothed him with the robe, and put the ephod on him; and he girded him with the intricately woven band of the ephod, and with it tied the ephod on him. 8 Then he put the breastplate on him, and he put the Urim and the Thummim in the breastplate. 9 And he put the turban on his head. Also on the turban, on its front, he put the golden plate, the holy crown, as the Lord had commanded Moses. 10 Also Moses took the anointing oil, and anointed the tabernacle and all that was in it, and consecrated them. 11 He sprinkled some of it on the altar seven times, 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 Then Moses brought Aaron's sons and put tunics on them, girded them with sashes, and put hats on them, as the Lord had commanded Moses.
14 And he brought the bull for the sin offering. Then Aaron and his sons laid their hands on the head of the bull for the sin offering, 15 and Moses killed it. Then he took the blood, and put some on the horns of the altar all around with his finger, and purified the altar. And he poured the blood at the base of the altar, and consecrated it, to make atonement for it. 16 Then he took all the fat that was on the entrails, the fatty lobe attached to the liver, and the two kidneys with their fat, and Moses burned them on the altar. 17 But the bull, its hide, its flesh, and its offal, he burned with fire outside the camp, as the Lord had commanded Moses. 18 Then he brought the ram as the burnt offering. And Aaron and his sons laid their hands on the head of the ram, 19 and Moses killed it. Then he sprinkled the blood all around on the altar. 20 And he cut the ram into pieces; and Moses burned the head, the pieces, and the fat. 21 Then he washed the entrails and the legs in water. And Moses burned the whole ram on the altar. It was a burnt sacrifice for a sweet aroma, an offering made by fire to the Lord, as the Lord had commanded Moses. 22 And he brought the second ram, the ram of consecration. Then Aaron and his sons laid their hands on the head of the ram, 23 and Moses killed it. Also he took some of its blood and put it on the tip of Aaron's right ear, on the thumb of his right hand, and on the big toe of his right foot. 24 Then he brought Aaron's sons. And Moses put some of the blood on the tips of their right ears, on the thumbs of their right hands, and on the big toes of their right feet. And Moses sprinkled the blood all around on the altar. 25 Then he took the fat and the fat tail, all the fat that was on the entrails, the fatty lobe attached to the liver, the two kidneys and their fat, and the right thigh; 26 and from the basket of unleavened bread that was before the Lord he took one unleavened cake, a cake of bread anointed with oil, and one wafer, and put them on the fat and on the right thigh; 27 and he put all these in Aaron's hands and in his sons' hands, and waved them as a wave offering before the Lord. 28 Then Moses took them from their hands and burned them on the altar, on the burnt offering. They were consecration offerings for a sweet aroma. That was an offering made by fire to the Lord. 29 And Moses took the breast and waved it as a wave offering before the Lord. It was Moses' part of the ram of consecration, as the Lord had commanded Moses. 30 Then Moses took some of the anointing oil and some of the blood which was on the altar, and sprinkled it on Aaron, on his garments, on his sons, and on the garments of his sons with him; and he consecrated Aaron, his garments, his sons, and the garments of his sons with him.

(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.

(Read Leviticus 8:14-36)
In these types we see our great High Priest, even Christ Jesus, solemnly appointed, anointed, and invested with his sacred office, by his own blood, and the influences of his Holy Spirit. He sanctifies the ordinances of religion, to the benefit of his people and the honour of God the Father; who for his sake accepts our worship, though it is polluted with sin. We may also rejoice, that he is a merciful and faithful High Priest, full of compassion to the feeble-minded and tempest-tossed soul. All true Christians are consecrated to be spiritual priests. We should seriously ask ourselves, whether in our daily walk we study to maintain this character? and abound in spiritual sacrifices, acceptable to God through Christ? If so, still there is no cause for boasting. Let us not despise our fellow-sinners; but remembering what we have done, and how we are saved, let us seek and pray for their salvation.
