Exodus 29:33 KJV

31And thou shalt take the ram of the consecration, and seethe his flesh in the holy place.

32And Aaron and his sons shall eat the flesh of the ram, and the bread that is in the basket, by the door of the tabernacle of the congregation.

33And they shall eat those things wherewith the atonement was made, to consecrate and to sanctify them: but a stranger shall not eat thereof, because they are holy.

34And if ought of the flesh of the consecrations, or of the bread, remain unto the morning, then thou shalt burn the remainder with fire: it shall not be eaten, because it is holy.

35And thus shalt thou do unto Aaron, and to his sons, according to all things which I have commanded thee: seven days shalt thou consecrate them.
