Leviticus 6:11

⁹And 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.

¹⁰It 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.

— Leviticus 6:11 —

¹²And the Lord spoke to Moses, saying,

¹³This is the gift of Aaron and of his sons, which they shall offer to the Lord in the day in which thou shalt 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.
