利未記 6:20

「當亞倫受膏的日子，他和他子孫所要獻給耶和華的供物，就是細麵伊法十分之一，為常獻的素祭：早晨一半，晚上一半。

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.
