Leviticus 6:16-21

¹⁶And Aaron and his sons shall eat that which is left of it: it shall be eaten without leaven in a holy place, they shall eat it in the court of the tabernacle of witness.

¹⁷It shall not be baked with leaven. I have given it as a portion to them of the burnt offerings of the Lord: it is most holy, as the offering for sin, and as the offering for trespass.

¹⁸Every male of the priests shall eat it: it is a perpetual ordinance throughout your generations of the burnt offerings of the Lord; whoever shall touch them shall be hallowed.

¹⁹And the Lord spoke to Moses, saying,

²⁰This is the gift of Aaron and of his sons, which they shall offer to the Lord in the day in which you shall anoint him; the tenth of an ephah of fine flour for a sacrifice continually, the half of it in the morning, and the half of it in the evening.

²¹It shall be made with oil in a frying-pan; he shall offer it kneaded and in rolls, an offering of fragments, an offering of a sweet savor to the Lord.
