Leviticus 2:8-10

You shall bring the grain offering that is made of these things to the LORD. And when it is presented to the priest, he shall bring it to the altar. Then the priest shall take from the grain offering a memorial portion, and burn it on the altar. It is an offering made by fire, a sweet aroma to the LORD. And what is left of the grain offering shall be Aaron’s and his sons’. It is most holy of the offerings to the LORD made by fire.
