Leviticus 2:2-3

²He shall bring it to Aaron’s sons, the priests. He shall take his handful of its fine flour, and of its oil, with all its frankincense, and the priest shall burn its memorial on the altar, an offering made by fire, of a pleasant aroma to the LORD.

³That which is left of the meal offering shall be Aaron’s and his sons’. It is a most holy part of the offerings of the LORD made by fire.
