Exodus

²⁷And thou shalt sanctify the breast of the wave offering, and the thigh of the heave offering, which is waved, and which is heaved up, of the ram of consecration, even of that which is for Aaron, and of that which is for his sons: ²⁸and it shall be for Aaron and his sons as a due for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifices of their peace offerings, even their heave offering unto the Lord. ²⁹And the holy garments of Aaron shall be for his sons after him, to be anointed in them, and to be consecrated in them. ³⁰Seven days shall the son that is priest in his stead put them on, when he cometh into the tent of meeting to minister in the holy place. ³¹And thou shalt take the ram of consecration, and seethe its flesh in a holy place. ³²And Aaron and his sons shall eat the flesh of the ram, and the bread that is in the basket, at the door of the tent of meeting. ³³And they shall eat those things wherewith atonement was made, to consecrate and to sanctify them: but a stranger shall not eat thereof, because they are holy.
