Leviticus 2:2-3

²And he shall bring it to Aaron’s sons the priests: and he shall take thereout his handful of the flour thereof, and of the oil thereof, with all the frankincense thereof; and the priest shall burn the memorial of it upon the altar, to be an offering made by fire, of a sweet savour unto the LORD:

³And the remnant of the meat offering shall be Aaron’s and his sons’: it is a thing most holy of the offerings of the LORD made by fire.
