Deuteronomy 10:8

And this is the thing that thou shalt do unto them to hallow them, to minister unto me in the priest's office: Take one young bullock, and two rams without blemish, And unleavened bread, and cakes unleavened tempered with oil, and wafers unleavened anointed with oil: of wheaten flour shalt thou make them. And thou shalt put them into one basket, and bring them in the basket, with the bullock and the two rams. And Aaron and his sons thou shalt bring unto the door of the tabernacle of the congregation, and shalt wash them with water. And thou shalt take the garments, and put upon Aaron the coat, and the robe of the ephod, and the ephod, and the breastplate, and gird him with the curious girdle of the ephod: And thou shalt put the mitre upon his head, and put the holy crown upon the mitre. Then shalt thou take the anointing oil, and pour it upon his head, and anoint him. And thou shalt bring his sons, and put coats upon them. And thou shalt gird them with girdles, Aaron and his sons, and put the bonnets on them: and the priest's office shall be theirs for a perpetual statute: and thou shalt consecrate Aaron and his sons. And thou shalt cause a bullock to be brought before the tabernacle of the congregation: and Aaron and his sons shall put their hands upon the head of the bullock. And thou shalt kill the bullock before the LORD, by the door of the tabernacle of the congregation. And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger, and pour all the blood beside the bottom of the altar. And thou shalt take all the fat that covereth the inwards, and the caul that is above the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar. But the flesh of the bullock, and his skin, and his dung, shalt thou burn with fire without the camp: it is a sin offering. Thou shalt also take one ram; and Aaron and his sons shall put their hands upon the head of the ram. And thou shalt slay the ram, and thou shalt take his blood, and sprinkle it round about upon the altar. And thou shalt cut the ram in pieces, and wash the inwards of him, and his legs, and put them unto his pieces, and unto his head. And thou shalt burn the whole ram upon the altar: it is a burnt offering unto the LORD: it is a sweet savor, an offering made by fire unto the LORD. And thou shalt take the other ram; and Aaron and his sons shall put their hands upon the head of the ram. Then shalt thou kill the ram, and take of his blood, and put it upon the tip of the right ear of Aaron, and upon the tip of the right ear of his sons, and upon the thumb of their right hand, and upon the great toe of their right foot, and sprinkle the blood upon the altar round about. And thou shalt take of the blood that is upon the altar, and of the anointing oil, and sprinkle it upon Aaron, and upon his garments, and upon his sons, and upon the garments of his sons with him: and he shall be hallowed, and his garments, and his sons, and his sons' garments with him. Also thou shalt take of the ram the fat and the rump, and the fat that covereth the inwards, and the caul above the liver, and the two kidneys, and the fat that is upon them, and the right shoulder; for it is a ram of consecration: And one loaf of bread, and one cake of oiled bread, and one wafer out of the basket of the unleavened bread that is before the LORD: And thou shalt put all in the hands of Aaron, and in the hands of his sons; and shalt wave them for a wave offering before the LORD. And thou shalt receive them of their hands, and burn them upon the altar for a burnt offering, for a sweet savor before the LORD: it is an offering made by fire unto the LORD. And thou shalt take the breast of the ram of Aaron's consecration, and wave it for a wave offering before the LORD: and it shall be thy part. And thou shalt sanctify the breast of the wave offering, and the shoulder of the heave offering, which is waved, and which is heaved up, of the ram of the consecration, even of that which is for Aaron, and of that which is for his sons: And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the LORD. And the holy garments of Aaron shall be his sons' after him, to be anointed therein, and to be consecrated in them. And that son that is priest in his stead shall put them on seven days, when he cometh into the tabernacle of the congregation to minister in the holy place. And thou shalt take the ram of the consecration, and seethe his flesh in the holy place. And Aaron and his sons shall eat the flesh of the ram, and the bread that is in the basket by the door of the tabernacle of the congregation. And they shall eat those things wherewith the atonement was made, to consecrate and to sanctify them: but a stranger shall not eat thereof, because they are holy. And if ought of the flesh of the consecrations, or of the bread, remain unto the morning, then thou shalt burn the remainder with fire: it shall not be eaten, because it is holy. And thus shalt thou do unto Aaron, and to his sons, according to all things which I have commanded thee: seven days shalt thou consecrate them. And thou shalt offer every day a bullock for a sin offering for atonement: and thou shalt cleanse the altar, when thou hast made an atonement for it, and thou shalt anoint it, to sanctify it. Seven days thou shalt make an atonement for the altar, and sanctify it; and it shall be an altar most holy: whatsoever toucheth the altar shall be holy.

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.

But the Levites after the tribe of their fathers were not numbered among them. For the LORD had spoken unto Moses, saying, Only thou shalt not number the tribe of Levi, neither take the sum of them among the children of Israel: But thou shalt appoint the Levites over the tabernacle of testimony, and over all the vessels thereof, and over all things that belong to it: they shall bear the tabernacle, and all the vessels thereof; and they shall minister unto it, and shall encamp round about the tabernacle. And when the tabernacle setteth forward, the Levites shall take it down: and when the tabernacle is to be pitched, the Levites shall set it up: and the stranger that cometh nigh shall be put to death. And the children of Israel shall pitch their tents, every man by his own camp, and every man by his own standard, throughout their hosts. But the Levites shall pitch round about the tabernacle of testimony, that there be no wrath upon the congregation of the children of Israel: and the Levites shall keep the charge of the tabernacle of testimony.

These also are the generations of Aaron and Moses in the day that the LORD spake with Moses in mount Sinai. And these are the names of the sons of Aaron; Nadab the firstborn, and Abihu, Eleazar, and Ithamar. These are the names of the sons of Aaron, the priests which were anointed, whom he consecrated to minister in the priest's office. And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father. And the LORD spake unto Moses, saying, Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him. And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle. And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, to do the service of the tabernacle. And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel. And thou shalt appoint Aaron and his sons, and they shall wait on their priest's office: and the stranger that cometh nigh shall be put to death. And the LORD spake unto Moses, saying, And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn that openeth the matrix among the children of Israel: therefore the Levites shall be mine; Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the LORD. And the LORD spake unto Moses in the wilderness of Sinai, saying, Number the children of Levi after the house of their fathers, by their families: every male from a month old and upward shalt thou number them. And Moses numbered them according to the word of the LORD, as he was commanded. And these were the sons of Levi by their names; Gershon, and Kohath, and Merari. And these are the names of the sons of Gershon by their families; Libni, and Shimei. And the sons of Kohath by their families; Amram, and Izehar, Hebron, and Uzziel. And the sons of Merari by their families; Mahli, and Mushi. These are the families of the Levites according to the house of their fathers. Of Gershon was the family of the Libnites, and the family of the Shimites: these are the families of the Gershonites. Those that were numbered of them, according to the number of all the males, from a month old and upward, even those that were numbered of them were seven thousand and five hundred. The families of the Gershonites shall pitch behind the tabernacle westward. And the chief of the house of the father of the Gershonites shall be Eliasaph the son of Lael. And the charge of the sons of Gershon in the tabernacle of the congregation shall be the tabernacle, and the tent, the covering thereof, and the hanging for the door of the tabernacle of the congregation, And the hangings of the court, and the curtain for the door of the court, which is by the tabernacle, and by the altar round about, and the cords of it for all the service thereof. And of Kohath was the family of the Amramites, and the family of the Izeharites, and the family of the Hebronites, and the family of the Uzzielites: these are the families of the Kohathites. In the number of all the males, from a month old and upward, were eight thousand and six hundred, keeping the charge of the sanctuary. The families of the sons of Kohath shall pitch on the side of the tabernacle southward. And the chief of the house of the father of the families of the Kohathites shall be Elizaphan the son of Uzziel. And their charge shall be the ark, and the table, and the candlestick, and the altars, and the vessels of the sanctuary wherewith they minister, and the hanging, and all the service thereof. And Eleazar the son of Aaron the priest shall be chief over the chief of the Levites, and have the oversight of them that keep the charge of the sanctuary.
