Exodus 29:26–34

²⁶“You shall take the breast of the ram of Aaron’s ordination and raise it as an elevation offering before the Lord, and it shall be your portion.^{* 27}You shall consecrate the breast that was raised as an elevation offering and the thigh that was lifted up as an offering from the ram of ordination, from that which belonged to Aaron and his sons.^{* 28}These things shall be a perpetual ordinance for Aaron and his sons from the Israelites, for this is an offering, and it shall be an offering by the Israelites from their sacrifice of offerings of well-being, their offering to the Lord.^*

²⁹“The sacred vestments of Aaron shall be passed on to his sons after him; they shall be anointed in them and ordained in them.^{* 30}The son who is priest in his place shall wear them seven days when he comes into the tent of meeting to minister in the holy place.^*

³¹“You shall take the ram of ordination and boil its flesh in a holy place,^{* 32}and Aaron and his sons shall eat the flesh of the ram and the bread that is in the basket at the entrance of the tent of meeting.^{* 33}They shall eat the food by which atonement is made, to ordain and consecrate them, but no one else shall eat of it, because it is holy.^{* 34}If any of the flesh for the ordination or of the bread remains until the morning, then you shall burn the remainder with fire; it shall not be eaten, because it is holy.^*
