The Bible – Old Testament
“This is the rite you shall perform in consecrating them as my priests. Procure a young bull and two unblemished rams.
With fine wheat flour make unleavened cakes mixed with oil, and unleavened wafers spread with oil,
and put them in a basket. Take the basket of them along with the bullock and the two rams.
Aaron and his sons you shall also bring to the entrance of the meeting tent, and there wash them with water.
Take the vestments and clothe Aaron with the tunic, the robe of the ephod, the ephod itself, and the breastpiece, fastening the embroidered belt of the ephod around him.
Put the miter on his head, the sacred diadem on the miter.
Then take the anointing oil and anoint him with it, pouring it on his head.
Bring forward his sons also and clothe them with the tunics,
gird them with the sashes, and tie the turbans on them. Thus shall the priesthood be theirs by perpetual law, and thus shall you ordain Aaron and his sons.
“Now bring forward the bullock in front of the meeting tent. There Aaron and his sons shall lay their hands on its head.
Then slaughter the bullock before the LORD, at the entrance of the meeting tent.
Take some of its blood and with your finger put it on the horns of the altar. All the rest of the blood you shall pour out at the base of the altar.
All the fat that covers its inner organs, as well as the lobe of its liver and its two kidneys, together with the fat that is on them, you shall take and burn on the altar.
But the flesh and hide and offal of the bullock you must burn up outside the camp, since this is a sin offering.
“Then take one of the rams, and after Aaron and his sons have laid their hands on its head,
slaughter it. The blood you shall take and splash on all the sides of the altar.
Cut the ram into pieces; its inner organs and shanks you shall first wash, and then put them with the pieces and with the head.
The entire ram shall then be burned on the altar, since it is a holocaust, a sweet-smelling oblation to the LORD.
“After this take the other ram, and when Aaron and his sons have laid their hands on its head,
slaughter it. Some of its blood you shall take and put on the tip of Aaron’s right ear and on the tips of his sons’ right ears and on the thumbs of their right hands and the great toes of their right feet. Splash the rest of the blood on all the sides of the altar.
Then take some of the blood that is on the altar, together with some of the anointing oil, and sprinkle this on Aaron and his vestments, as well as on his sons and their vestments, that his sons and their vestments may be sacred.
1 “Now, from this ram you shall take its fat: its fatty tail, the fat that covers its inner organs, the lobe of its liver, its two kidneys with the fat that is on them, and its right thigh, since this is the ordination ram;
then, out of the basket of unleavened food that you have set before the LORD, you shall take one of the loaves of bread, one of the cakes made with oil, and one of the wafers.
2 All these things you shall put into the hands of Aaron and his sons, so that they may wave them as a wave offering before the LORD.
After you have received them back from their hands, you shall burn them on top of the holocaust on the altar as a sweet-smelling oblation to the LORD.
Finally, take the breast of Aaron’s ordination ram and wave it as a wave offering before the LORD; this is to be your own portion.
3 “Thus shall you set aside the breast of whatever wave offering is waved, as well as the thigh of whatever raised offering is raised up, whether this be the ordination ram or anything else belonging to Aaron or to his sons.
Such things are due to Aaron and his sons from the Israelites by a perpetual ordinance as a contribution. From their peace offerings, too, the Israelites shall make a contribution, their contribution to the LORD.
“The sacred vestments of Aaron shall be passed down to his descendants, that in them they may be anointed and ordained.
The descendant who succeeds him as priest and who is to enter the meeting tent to minister in the sanctuary shall be clothed with them for seven days.
“You shall take the flesh of the ordination ram and boil it in a holy place.
At the entrance of the meeting tent Aaron and his sons shall eat the flesh of the ram and the bread that is in the basket.
They themselves are to eat of these things by which atonement was made at their ordination and consecration; but no layman may eat of them, since they are sacred.
If some of the flesh of the ordination sacrifice or some of the bread remains over on the next day, this remnant must be burned up; it is not to be eaten, since it is sacred.
Carry out all these orders in regard to Aaron and his sons just as I have given them to you. “Seven days you shall spend in ordaining them,
4 sacrificing a bullock each day as a sin offering, to make atonement. Thus also shall you purge the altar in making atonement for it; you shall anoint it in order to consecrate it.
Seven days you shall spend in making atonement for the altar and in consecrating it. Then the altar will be most sacred, and whatever touches it will become sacred.
5 “Now, this is what you shall offer on the altar: two yearling lambs as the sacrifice established for each day;
one lamb in the morning and the other lamb at the evening twilight.
With the first lamb there shall be a tenth of an ephah of fine flour mixed with a fourth of a hin of oil of crushed olives and, as its libation, a fourth of a hin of wine.
The other lamb you shall offer at the evening twilight, with the same cereal offering and libation as in the morning. You shall offer this as a sweet-smelling oblation to the LORD.
Throughout your generations this established holocaust shall be offered before the LORD at the entrance of the meeting tent, where I will meet you and speak to you.
“There, at the altar, I will meet the Israelites; hence, it will be made sacred by my glory.
Thus I will consecrate the meeting tent and the altar, just as I also consecrate Aaron and his sons to be my priests.
I will dwell in the midst of the Israelites and will be their God.
They shall know that I, the LORD, am their God who brought them out of the land of Egypt, so that I, the LORD, their God, might dwell among them.
1  Fatty tail: the thick layer of fat surrounding the tails of sheep and rams bred in Palestine even today. It is regarded as a choice food. Cf ⇒ Lev 3:9.
2 [24-26] Wave offering: the portions of a peace offering, breast and right thigh, which the officiating priest moved to and fro (waved) in the presence of the Lord. They were reserved for Aaron and his sons.
4 [36,37] Purge the altar: the construction of an altar by profane hands rendered it impure. The anointing and consecration of the altar purified it and made it sacred.
