Leviticus 2:8-10

Amplified Bible

⁸ When you bring the grain offering that is made of these things to the Lord, it shall be presented to the priest, and he shall bring it to the altar [of burnt offering]. ⁹ The priest shall take from the grain offering its memorial portion and offer it up in smoke on the altar. It is an offering by fire, a sweet and soothing aroma to the Lord. ¹⁰ What is left of the grain offering belongs to Aaron and his sons; it is a most holy part of the offerings to the Lord by fire.
