John Gill Commentary Leviticus 2:9

"And the priest shall take up from the meal-offering the memorial thereof, and shall burn it upon the altar, an offering made by fire, of a sweet savor unto Jehovah." — Leviticus 2:9 (ASV)

And the priest shall take from the meat offering a memorial
thereof
That is, an handful of it; as of the fine flour, (Leviticus 2:2) so of the pieces of that which was baked, whether in the oven, or pan, or fryingpan:

and shall burn it upon the altar ;
the memorial or handful:

[it is] an offering made by fire, of a sweet savour unto the Lord ;
(See Gill on Leviticus 1:9).
