Leviticus 6:16-17

CAB(i) 16 And 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. 17 It 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.
