Leviticus 6:22-26

²²Soothly the priest which is successor to his father, shall offer it hot, into the sweetest odour to the Lord; and all it shall be burnt in the altar.

²³For all the sacrifice of priests shall be burnt with fire, neither any man shall eat thereof.

²⁴And the Lord spake to Moses, and said,

²⁵Speak thou to Aaron and to his sons, This is the law of sacrifice for sin; it shall be offered before the Lord, in the place where burnt sacrifice is offered; it is holy of holy things.

²⁶The priest that offereth it, shall eat it in the holy place, in the great porch of the tabernacle.
