Leviticus 6:16-20

¹⁶(6:9) And what is left thereof shall Aaron and his sons eat: unleavened shall it be eaten in a holy place; in the court of the tabernacle of the congregation shall they eat it.

¹⁷(6:10) It shall not be baked leaven; as their portion have I given it from my offerings made by fire; it is most holy, as is the sin-offering, and as is the trespass-offering.

¹⁸(6:11) all the males among the children of Aaron shall eat of it, as a fixed portion for ever in your generations from the fire-offerings of the Lord: every one that toucheth the same shall be holy.

¹⁹(6:12) And the Lord spoke unto Moses, saying,

²⁰(6:13) This is the offering of Aaron and of his sons, which they shall offer unto the Lord on the day when he is anointed: the tenth part of an ephah of fine flour for a meat-offering perpetually; half of it in the morning, and the other half of it in the evening.
