Leviticus 6:16-18 New Revised Standard Version, Anglicised (NRSVA)
16 Aaron and his sons shall eat what is left of it; it shall be eaten as unleavened cakes in a holy place; in the court of the tent of meeting they shall eat it. 17 It shall not be baked with leaven. I have given it as their portion of my offerings by fire; it is most holy, like the sin-offering and the guilt-offering. 18 Every male among the descendants of Aaron shall eat of it, as their perpetual due throughout your generations, from the Lord’s offerings by fire; anything that touches them shall become holy.
