Leviticus 2:2-3

²and he hath brought it in unto the sons of Aaron, the priests, and he hath taken from thence the fulness of his hand of its flour and of its oil, besides all its frankincense, and the priest hath made perfume with its memorial on the altar, a fire-offering of sweet fragrance to Jehovah;

³and the remnant of the present is for Aaron and for his sons, most holy, of the fire-offerings of Jehovah.
