Leviticus 6:18-20

Authorized (King James) Version

¹⁸ All the males among the children of Aaron shall eat of it. It shall be a statute for ever in your generations concerning the offerings of the Lord made by fire: every one that toucheth them shall be holy.

¹⁹ And the Lord spake unto Moses, saying, ²⁰ This is the offering 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 meat offering perpetual, half of it in the morning, and half thereof at night.
