Leviticus 6:16-18

CLV(i) 16 And the rest of it Aaron and his sons shall eat. As unleavened cakes shall it be eaten in a holy place. In the court of the tent of appointment shall they eat it. 17 It shall not be baked with leaven. As their portion I give it from My fire offering. It is a holy of holies, like the sin offering and like the guilt offering. 18 Every male among the sons of Aaron may eat of it. It is an eonian statute throughout your generations from the fire offerings of Yahweh. All that may touch them is holy.
