Exodus 29:1-37
“ Now this is what you are to do for them to consecrate them so that they may minister as my priests. Take a young bull and two rams without blemish;and bread made without yeast, and perforated cakes without yeast mixed with oil, and wafers without yeast spread with oil– you are to make them using fine wheat flour.You are to put them in one basket and present them in the basket, along with the bull and the two rams.“ You are to present Aaron and his sons at the entrance of the tent of meeting. You are to wash them with waterand take the garments and clothe Aaron with the tunic, the robe of the ephod, the ephod, and the breastpiece; you are to fasten the ephod on him by using the skillfully woven waistband.You are to put the turban on his head and put the holy diadem on the turban.You are to take the anointing oil and pour it on his head and anoint him.You are to present his sons and clothe them with tunicsand wrap the sashes around Aaron and his sons and put headbands on them, and so the ministry of priesthood will belong to them by a perpetual ordinance. Thus you are to consecrate Aaron and his sons.“ You are to present the bull at the front of the tent of meeting, and Aaron and his sons are to put their hands on the head of the bull.You are to kill the bull before the LORD at the entrance to the tent of meetingand take some of the blood of the bull and put it on the horns of the altar with your finger; all the rest of the blood you are to pour out at the base of the altar.You are to take all the fat that covers the entrails, and the lobe that is above the liver, and the two kidneys and the fat that is on them, and burn them on the altar.But the meat of the bull, its skin, and its dung you are to burn up outside the camp. It is the purification offering.“ You are to take one ram, and Aaron and his sons are to lay their hands on the ram’s head,and you are to kill the ram and take its blood and splash it all around on the altar.Then you are to cut the ram into pieces and wash the entrails and its legs and put them on its pieces and on its headand burn the whole ram on the altar. It is a burnt offering to the LORD, a soothing aroma; it is an offering made by fire to the LORD.“ You are to take the second ram, and Aaron and his sons are to lay their hands on the ram’s head,and you are to kill the ram and take some of its blood and put it on the tip of the right ear of Aaron, on the tip of the right ear of his sons, on the thumb of their right hand, and on the big toe of their right foot, and then splash the blood all around on the altar.You are to take some of the blood that is on the altar and some of the anointing oil and sprinkle it on Aaron, on his garments, on his sons, and on his sons’ garments with him, so that he may be holy, he and his garments along with his sons and his sons’ garments.“ You are to take from the ram the fat, the fat tail, the fat that covers the entrails, the lobe of the liver, the two kidneys and the fat that is on them, and the right thigh– for it is the ram for consecration–and one round flat cake of bread, one perforated cake of oiled bread, and one wafer from the basket of bread made without yeast that is before the LORD.You are to put all these in Aaron’s hands and in his sons’ hands, and you are to wave them as a wave offering before the LORD.Then you are to take them from their hands and burn them on the altar for a burnt offering, for a soothing aroma before the LORD. It is an offering made by fire to the LORD.You are to take the breast of the ram of Aaron’s consecration; you are to wave it as a wave offering before the LORD, and it is to be your share.You are to sanctify the breast of the wave offering and the thigh of the contribution, which were waved and lifted up as a contribution from the ram of consecration, from what belongs to Aaron and to his sons.It is to belong to Aaron and to his sons from the Israelites, by a perpetual ordinance, for it is a contribution. It is to be a contribution from the Israelites from their peace offerings, their contribution to the LORD.“ The holy garments that belong to Aaron are to belong to his sons after him, so that they may be anointed in them and consecrated in them.The priest who succeeds him from his sons, when he first comes to the tent of meeting to minister in the Holy Place, is to wear them for seven days.“ You are to take the ram of the consecration and cook its meat in a holy place.Aaron and his sons are to eat the meat of the ram and the bread that was in the basket at the entrance of the tent of meeting.They are to eat those things by which atonement was made to consecrate and to set them apart, but no one else may eat them, for they are holy.If any of the meat from the consecration offerings or any of the bread is left over until morning, then you are to burn up what is left over. It must not be eaten, because it is holy.“ Thus you are to do for Aaron and for his sons, according to all that I have commanded you; you are to consecrate them for seven days.Every day you are to prepare a bull for a purification offering for atonement. You are to purge the altar by making atonement for it, and you are to anoint it to set it apart as holy.For seven days you are to make atonement for the altar and set it apart as holy. Then the altar will be most holy. Anything that touches the altar will be holy.
Numbers 18:1-7
The LORD said to Aaron,“ You and your sons and your tribe with you must bear the iniquity of the sanctuary, and you and your sons with you must bear the iniquity of your priesthood.“ Bring with you your brothers, the tribe of Levi, the tribe of your father, so that they may join with you and minister to you while you and your sons with you are before the tent of the testimony.They must be responsible to care for you and to care for the entire tabernacle. However, they must not come near the furnishings of the sanctuary and the altar, or both they and you will die.They must join with you, and they will be responsible for the care of the tent of meeting, for all the service of the tent, but no unauthorized person may approach you.You will be responsible for the care of the sanctuary and the care of the altar, so that there will be no more wrath on the Israelites.I myself have chosen your brothers the Levites from among the Israelites. They are given to you as a gift from the LORD, to perform the duties of the tent of meeting.But you and your sons with you are responsible for your priestly duties, for everything at the altar and within the curtain. And you must serve. I give you the priesthood as a gift for service; but the unauthorized person who approaches must be put to death.”
