Exodus 29:27-34

29:27 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. 29:28 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.

29:29 “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. 29:30 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.

29:31 “You are to take the ram of the consecration and cook its meat in a holy place. 29:32 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. 29:33 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. 29:34 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.
