Leviticus 6:18-20

Amplified Bible

¹⁸ Every male among the sons of Aaron may eat it [as his share]; it is a permanent ordinance throughout your generations, from offerings by fire to the Lord. ^[a]Whatever touches them will become consecrated (ceremonially clean).’”

¹⁹ Then the Lord spoke to Moses, saying, ²⁰ “This is the offering which Aaron and his sons are to present to the Lord on the day when he is anointed: the tenth of an ephah of fine flour as a regular grain offering, half of it in the morning and half of it in the evening.
