8 And he put the priest's bag on him, and in the bag he put the Urim and Thummim. 9 And on his head he put the head-dress, and in front of the head-dress the plate of gold, the holy crown, as the Lord gave orders to Moses. 10 And Moses took the holy oil and put it on the House and on all the things in it, to make them holy. 11 Seven times he put oil on the altar and on all its vessels, and on the washing-basin and its base, to make them holy. 12 And some of the oil he put on Aaron's head, to make him holy. 13 Then he took Aaron's sons, clothing them with the coats, and putting the bands round them, and the head-dresses on their heads, as the Lord had given him orders.

14 And he took the ox of the sin-offering: and Aaron and his sons put their hands on the head of the ox, 15 And he put it to death; and Moses took the blood and put it on the horns of the altar and round it with his finger, and made the altar clean, draining out the blood at the base of the altar; so he made it holy, taking away what was unclean. 16 And he took all the fat on the inside parts, and the fat on the liver, and the two kidneys with their fat, to be burned on the altar; 17 But the ox, with its skin and its flesh and its waste, was burned with fire outside the tent-circle, as the Lord gave orders to Moses. 18 And he put the male sheep of the burned offering before the Lord, and Aaron and his sons put their hands on its head, 19 And he put it to death; and Moses put some of the blood on and round the altar. 20 And when the sheep had been cut into parts, the head and the parts and the fat were burned by Moses. 21 And the inside parts and the legs were washed with water and all the sheep was burned by Moses on the altar; it was a burned offering for a sweet smell: it was an offering made by fire to the Lord, as the Lord gave orders to Moses.

Matthew Henry's Commentary on Leviticus 8:8-21

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.
