Leviticus 2:1-3

“When you present a Grain-Offering to GOD, use fine flour. Pour oil on it, put incense on it, and bring it to Aaron’s sons, the priests. One of them will take a handful of the fine flour and oil, with all the incense, and burn it on the Altar for a memorial: a Fire-Gift, a pleasing fragrance to GOD. The rest of the Grain-Offering is for Aaron and his sons—a most holy part of the Fire-Gifts to GOD.
