Leviticus 6:18-20

Darby Translation

¹⁸ All the males among the children of Aaron shall eat of it. [It is] an everlasting statute in your generations, [their portion] of Jehovah's offerings by fire: whatever toucheth these shall be holy.

¹⁹ And Jehovah spoke to Moses, saying,

²⁰ This is the offering of Aaron and of his sons, which they shall present to Jehovah on the day when he is anointed: the tenth part of an ephah of fine flour as a continual oblation, half of it in the morning, and half thereof at night.
