Leviticus 6:20-22
20
"This is the offering of Aaron and of his sons, which they shall offer to Yahweh in the day when he is anointed: the tenth part of an ephah of fine flour for a meal offering perpetually, half of it in the morning, and half of it in the evening.
21
It shall be made with oil in a griddle. When it is soaked, you shall bring it in. You shall offer the meal offering in baked pieces for a pleasant aroma to Yahweh.
22
The anointed priest that will be in his place from among his sons shall offer it. By a statute forever, it shall be wholly burnt to Yahweh.
