Leviticus 2:2, 9, 16

He shall bring it to Aaron’s sons, the priests, one of whom shall take from it his handful of fine flour and oil with all the frankincense. And the priest shall burn it as a memorial on the altar, an offering made by fire, a sweet aroma to the LORD.

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.

Then the priest shall burn the memorial portion: part of its beaten grain and part of its oil, with all the frankincense, as an offering made by fire to the LORD.
