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.
14 He brought the bull of the sin offering, and Aaron and his sons laid their hands on the head of the bull of the sin offering. 15 He killed it; and Moses took the blood, and put it around on the horns of the altar with his finger, and purified the altar, and poured out the blood at the base of the altar, and sanctified it, to make atonement for it. 16 He took all the fat that was on the innards, and the cover of the liver, and the two kidneys, and their fat; and Moses burned it on the altar. 17 But the bull, and its skin, and its flesh, and its dung, he burned with fire outside the camp; as Yahweh commanded Moses. 18 He presented the ram of the burnt offering: and Aaron and his sons laid their hands on the head of the ram. 19 He killed it; and Moses sprinkled the blood around on the altar. 20 He cut the ram into its pieces; and Moses burned the head, and the pieces, and the fat. 21 He washed the innards and the legs with water; and Moses burned the whole ram on the altar. It was a burnt offering for a pleasant aroma. It was an offering made by fire to Yahweh; 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.
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.
