Leviticus 2:8-10

2:8 “‘You must bring the grain offering that must be made from these to the Lord. Present it to the priest, and he will bring it to the altar. 2:9 Then the priest must take up from the grain offering its memorial portion and offer it up in smoke on the altar – it is a gift of a soothing aroma to the Lord. 2:10 The remainder of the grain offering belongs to Aaron and to his sons – it is most holy from the gifts of the Lord.
