1.

And the LORD spake unto Moses, saying,

2.

Take Aaron and his sons with him, and the garments, and the anointing oil, and a bullock for the sin offering, and two rams, and a basket of unleavened bread;

A bullock ... two rams ... a basket - compare Exodus 29:1-3. This shows the coherence of this part of Leviticus with the latter part of Exodus. The basket of unleavened bread used on this occasion appears to have contained:
(1) cakes or loaves of the ordinary unleavened bread;
(2) cakes of oiled bread, rather, oil bread (see Leviticus 2:1, Leviticus 2:4); and
(3) oiled wafers (see Leviticus 2:4, Leviticus 2:6).
Rabbinical tradition says that there were six cakes of each sort.

3.

And gather thou all the congregation together unto the door of the tabernacle of the congregation.

Gather ... - Rather, gather all the assembly together toward the entrance of the tent of meeting. See Leviticus 4:13. The whole body of the people were summoned on this occasion, and the elders probably occupied the first places. The elders are especially called together in an unequivocal manner to receive directions to provide the first sacrifices for the nation to be offered by the newly consecrated priests Leviticus 9:1, and the body of the people afterward assemble as they do here Leviticus 9:5. The spot designated was the portion of the court in front of the tabernacle (see Leviticus 1:3 note). Toward this space the people were commanded to assemble to witness the great national ceremony of the consecration of the priesthood, the solemn setting apart of one of their families, the members of which were henceforth to stand as mediators between them and Yahweh in carrying out the precepts of the ceremonial law. Those who could do so, may have come into the court, and a great number of others may have occupied the heights which overlooked the enclosure of the court. As the series of ceremonies was repeated every day during a week Leviticus 8:33, it is natural to suppose that some of the people attended on one day and some on another.

4.

And Moses did as the LORD commanded him; and the assembly was gathered together unto the door of the tabernacle of the congregation.

5.

And Moses said unto the congregation, This is the thing which the LORD commanded to be done.

6.

And Moses brought Aaron and his sons, and washed them with water.

Washed them with water - Moses caused them to bathe entirely (compare Leviticus 16:4), not merely to wash their hands and feet, as they were to do in their daily ministrations. See the marginal reference. This bathing, which the high priest had also to go through on the day of atonement, was symbolic of the spiritual cleansing required of all 2 Corinthians 7:1, but especially of those who had to draw near to God to make reconciliation for the sins of the people Hebrews 7:26; Matthew 3:15.

7.

And he put upon him the coat, and girded him with the girdle, and clothed him with the robe, and put the ephod upon him, and he girded him with the curious girdle of the ephod, and bound it unto him therewith.

8.

And he put the breastplate upon him: also he put in the breastplate the Urim and the Thummim.

9.

And he put the mitre upon his head; also upon the mitre, even upon his forefront, did he put the golden plate, the holy crown; as the LORD commanded Moses.

10.

And Moses took the anointing oil, and anointed the tabernacle and all that was therein, and sanctified them.

Moses first anointed with the holy oil Exodus 30:25 the tabernacle and all therein, that is, the ark of the covenant, the table of showbread, the candlestick and the golden altar, with all the articles that belonged to them.

11.

And he sprinkled thereof upon the altar seven times, and anointed the altar and all his vessels, both the laver and his foot, to sanctify them.

Sprinkled ... the altar seven times - The altar of burnt-offering was distinguished by this sevenfold sprinkling with the holy oil. The number of the covenant was thus brought into connection with those acts of sacrifice by which the covenant between Yahweh and the worshipper was formally renewed and confirmed.

12.

And he poured of the anointing oil upon Aaron's head, and anointed him, to sanctify him.

As investing the priest with official garments was a recognition before men of the official position of the person (see Exodus 28:3 note), so the anointing him with oil was an acknowledgment that all fitness for his office, all the powers with which he would rightly fulfill its duties, must come from the Lord.
So, again, with the sanctification of the holy things. Each of them was intended by divine wisdom to convey a spiritual meaning to the mind of man. They were means of grace to the devout worshipper. The oil poured upon them was a recognition of this fact, and at the same time it made them holy and set them apart from all profane and ordinary uses. On kindred grounds, though to express another idea, the altar was to be sanctified also by blood. See Leviticus 8:15 note.

13.

And Moses brought Aaron's sons, and put coats upon them, and girded them with girdles, and put bonnets upon them; as the LORD commanded Moses.

Aaron’s sons - The common priests. Nothing is said here, or in Exodus 29:7-9, of the anointing of the common priests, though it is expressly commanded in Exodus 28:41; Exodus 40:15, and is evidently implied as a fact in Leviticus 7:36; Leviticus 10:7; Numbers 3:3. It would seem that the anointing of the common priests consisted in some rite common to them and the high priest Exodus 40:15, and this was the sprinkling mentioned in Leviticus 8:30. Compare further Leviticus 10:7 with Leviticus 21:12.

14.

And he brought the bullock for the sin offering: and Aaron and his sons laid their hands upon the head of the bullock for the sin offering.

15.

And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured the blood at the bottom of the altar, and sanctified it, to make reconciliation upon it.

16.

And he took all the fat that was upon the inwards, and caul above the liver, and the two kidneys, and their fat, and Moses burned it upon the altar.

17.

But the bullock, and his hide, his flesh, and his dung, he burnt with fire without the camp; as the LORD commanded Moses.

18.

And he brought the ram for the burnt offering: and Aaron and his sons laid their hands upon the head of the ram.

19.

And he killed it; and Moses sprinkled the blood upon the altar round about.

20.

And he cut the ram into pieces; and Moses burnt the head, and the pieces, and the fat.

21.

And he washed the inwards and the legs in water; and Moses burnt the whole ram upon the altar: it was a burnt sacrifice for a sweet savour, and an offering made by fire unto the LORD; as the LORD commanded Moses.

22.

And he brought the other ram, the ram of consecration: and Aaron and his sons laid their hands upon the head of the ram.

23.

And he slew it; and Moses took of the blood of it, and put it upon the tip of Aaron's right ear, and upon the thumb of his right hand, and upon the great toe of his right foot.

24.

And he brought Aaron's sons, and Moses put of the blood upon the tip of their right ear, and upon the thumbs of their right hands, and upon the great toes of their right feet: and Moses sprinkled the blood upon the altar round about.

25.

And he took the fat, and the rump, and all the fat that was upon the inwards, and the caul above the liver, and the two kidneys, and their fat, and the right shoulder:

26.

And out of the basket of unleavened bread, that was before the LORD, he took one unleavened cake, and a cake of oiled bread, and one wafer, and put them on the fat, and upon the right shoulder:

27.

And he put all upon Aaron's hands, and upon his sons' hands, and waved them for a wave offering before the LORD.

28.

And Moses took them from off their hands, and burnt them on the altar upon the burnt offering: they were consecrations for a sweet savour: it is an offering made by fire unto the LORD.

29.

And Moses took the breast, and waved it for a wave offering before the LORD: for of the ram of consecration it was Moses' part; as the LORD commanded Moses.

30.

And Moses took of the anointing oil, and of the blood which was upon the altar, and sprinkled it upon Aaron, and upon his garments, and upon his sons, and upon his sons' garments with him; and sanctified Aaron, and his garments, and his sons, and his sons' garments with him.

31.

And Moses said unto Aaron and to his sons, Boil the flesh at the door of the tabernacle of the congregation: and there eat it with the bread that is in the basket of consecrations, as I commanded, saying, Aaron and his sons shall eat it.

32.

And that which remaineth of the flesh and of the bread shall ye burn with fire.

33.

And ye shall not go out of the door of the tabernacle of the congregation in seven days, until the days of your consecration be at an end: for seven days shall he consecrate you.

34.

As he hath done this day, so the LORD hath commanded to do, to make an atonement for you.

35.

Therefore shall ye abide at the door of the tabernacle of the congregation day and night seven days, and keep the charge of the LORD, that ye die not: for so I am commanded.

36.

So Aaron and his sons did all things which the LORD commanded by the hand of Moses.
