Leviticus 6:20

Lev 6:20 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.

Ver. 20. When he is anointed, ] i.e., When any high priest: for he only was anointed, Exo 29:7 on the head at least.
