Leviticus 2:1-3

1‘Now when anyone presents a 1grain offering as an offering to the Lord, his offering shall be of fine flour, and he shall pour oil on it and put frankincense on it. 2He shall then bring it to Aaron’s sons the priests; and he shall take from it 2his handful of its fine flour and of its oil, with all of its frankincense. And the priest shall offer it up in smoke as its 3memorial portion on the altar, an offering by fire of a soothing aroma to the Lord. 34The remainder of the grain offering belongs to 5Aaron and his sons: a most holy part of the offerings to the Lord by fire.
