Exodus 29:35

32 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.

33 They shall eat those things with which atonement was made, to consecrate and sanctify them: but a stranger shall not eat of it, because they are holy.

34 If anything of the flesh of the consecration, or of the bread, remains to the morning, then you shall burn the remainder with fire: it shall not be eaten, because it is holy.

35 "Thus shall you do to Aaron, and to his sons, according to all that I have commanded you. Seven days shall you consecrate them.

36 Every day shall you offer the bull of sin-offering for atonement: and you shall cleanse the altar, when you make atonement for it; and you shall anoint it, to sanctify it.

37 Seven days you shall make atonement for the altar, and sanctify it: and the altar shall be most holy; whatever touches the altar shall be holy.

38 "Now this is that which you shall offer on the altar: two lambs a year old day by day continually.
