Leviticus [Pertaining to Levites] 2:2-3

²He shall bring it to Aaron Light-bringer’s sons, the priests; and 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 Adonai .

³That which is left of the meal offering shall be Aaron Light-bringer’s and his sons’. It is a most holy thing of the offerings of Adonai made by fire.
