LEVITICUS 6:16-20

¹⁶And that which is left thereof shall Aaron and his sons eat: it shall be eaten without leaven in a holy place; in the court of the tent of meeting they shall eat it.

¹⁷It shall not be baken with leaven. I have given it as their portion of my offerings made by fire; it is most holy, as the sin offering, and as the guilt offering.

¹⁸Every male among the children of Aaron shall eat of it, as a due for ever throughout your generations, from the offerings of the LORD made by fire: whosoever toucheth them shall be holy.

¹⁹And the LORD spake unto Moses, saying,

²⁰This is the oblation of Aaron and of his sons, which they shall offer unto the LORD in the day when he is anointed; the tenth part of an ephah of fine flour for a meal offering perpetually, half of it in the morning, and half thereof in the evening.
