Exodus 29:24-37

Put all these in the hands of Aaron and his sons to be lifted up as a special offering to the LORD. Afterward take the various breads from their hands, and burn them on the altar along with the burnt offering. It is a pleasing aroma to the LORD, a special gift for him. Then take the breast of Aaron’s ordination ram, and lift it up in the LORD’s presence as a special offering to him. Then keep it as your own portion. “Set aside the portions of the ordination ram that belong to Aaron and his sons. This includes the breast and the thigh that were lifted up before the LORD as a special offering. In the future, whenever the people of Israel lift up a peace offering, a portion of it must be set aside for Aaron and his descendants. This is their permanent right, and it is a sacred offering from the Israelites to the LORD. “Aaron’s sacred garments must be preserved for his descendants who succeed him, and they will wear them when they are anointed and ordained. The descendant who succeeds him as high priest will wear these clothes for seven days as he ministers in the Tabernacle and the Holy Place. “Take the ram used in the ordination ceremony, and boil its meat in a sacred place. Then Aaron and his sons will eat this meat, along with the bread in the basket, at the Tabernacle entrance. They alone may eat the meat and bread used for their purification in the ordination ceremony. No one else may eat them, for these things are set apart and holy. If any of the ordination meat or bread remains until the morning, it must be burned. It may not be eaten, for it is holy. “This is how you will ordain Aaron and his sons to their offices, just as I have commanded you. The ordination ceremony will go on for seven days. Each day you must sacrifice a young bull as a sin offering to purify them, making them right with the LORD. Afterward, cleanse the altar by purifying it; make it holy by anointing it with oil. Purify the altar, and consecrate it every day for seven days. After that, the altar will be absolutely holy, and whatever touches it will become holy.
