81 And the Lord said to Moses, 2 Take Aaron, and his sons with him, and the robes and the holy oil and the ox of the sin-offering and the two male sheep and the basket of unleavened bread; 3 And let all the people come together at the door of the Tent of meeting. 4 And Moses did as the Lord said, and all the people came together at the door of the Tent of meeting. 5 And Moses said to the people, This is what the Lord has given orders to be done. 6 Then Moses took Aaron and his sons; and after washing them with water, 7 He put the coat on him, making it tight with its band, and then the robe, and over it the ephod, with its band of needlework to keep it in place. 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. 22 And he put the other sheep before the Lord, the sheep with which they were made priests; and Aaron and his sons put their hands on the head of the sheep, 23 And he put it to death; and Moses took some of the blood and put it on the point of Aaron's right ear and on the thumb of his right hand and on the great toe of his right foot. 24 Then he took Aaron's sons, and Moses put some of the blood on the point of their right ears and on the thumbs of their right hands and on the great toes of their right feet: and Moses put the blood on and round the altar. 25 And he took the fat, and the fat tail, and the fat on the inside parts, and the fat on the liver, and the two kidneys with their fat, and the right leg; 26 And out of the basket of unleavened bread which was before the Lord he took one unleavened cake, and one cake of bread with oil on it, and one thin cake, and put them on the fat and on the right leg: 27 And he put them all on the hands of Aaron and on the hands of his sons, waving them for a wave offering before the Lord. 28 And Moses took them from their hands, and they were burned on the altar on the burned offering, as a priest's offering for a sweet smell, an offering made by fire to the Lord. 29 And Moses took the breast, waving it for a wave offering before the Lord; it was Moses' part of the sheep of the priest's offering, as the Lord gave orders to Moses. 30 And Moses took some of the holy oil and of the blood which was on the altar and put it on Aaron and on his robes, and on his sons and on his sons' robes; and made Aaron holy, and his robes and his sons and his sons' robes with 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.
