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.

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.
Commentary on Leviticus 8:14-36
(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.
