8 Then Moses placed the chestpiece on Aaron and put the Urim and the Thummim inside it. 9 He placed the turban on Aaron's head and attached the gold medallion-the badge of holiness-to the front of the turban, just as the Lord had commanded him. 10 Then Moses took the anointing oil and anointed the Tabernacle and everything in it, making them holy. 11 He sprinkled the oil on the altar seven times, anointing it and all its utensils, as well as the washbasin and its stand, making them holy. 12 Then he poured some of the anointing oil on Aaron's head, anointing him and making him holy for his work. 13 Next Moses presented Aaron's sons. He clothed them in their tunics, tied their sashes around them, and put their special head coverings on them, just as the Lord had commanded him.
14 Then Moses presented the bull for the sin offering. Aaron and his sons laid their hands on the bull's head, 15 and Moses slaughtered it. Moses took some of the blood, and with his finger he put it on the four horns of the altar to purify it. He poured out the rest of the blood at the base of the altar. Through this process, he made the altar holy by purifying it. 16 Then Moses took all the fat around the internal organs, the long lobe of the liver, and the two kidneys and the fat around them, and he burned it all on the altar. 17 He took the rest of the bull, including its hide, meat, and dung, and burned it on a fire outside the camp, just as the Lord had commanded him. 18 Then Moses presented the ram for the burnt offering. Aaron and his sons laid their hands on the ram's head, 19 and Moses slaughtered it. Then Moses took the ram's blood and splattered it against all sides of the altar. 20 Then he cut the ram into pieces, and he burned the head, some of its pieces, and the fat on the altar. 21 After washing the internal organs and the legs with water, Moses burned the entire ram on the altar as a burnt offering. It was a pleasing aroma, a special gift presented to the Lord, just as the Lord had commanded him.

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.
