Leviticus 2:10ESV·traditional attribution

But the rest of the grain offering shall be for Aaron and his sons; it is a most holy part of the LORD’s food offerings.

Matthew Henry Presbyterian @wholebiblehenry

There were some meat-offerings that were only appendices to the burnt-offerings, as that which was offered with the daily sacrifice (Exo 29:38, Exo 29:39) and with the peace-offerings; these had drink-offerings joined with them (see Num 15:4, Num 15:7, Num 15:9, Num 15:10), and in these the quantity was appointed.

John Gill Reformed Baptist @doctorgill

And that which is left of the meat offering,.... Not burnt with fire: shall be Aaron's and his sons'; the high priest took his part first, and then the common priests: it is a thing most holy of the offerings of the Lord made by fire; See Gill on Lev 2:3.

Lev 2:4-11 The second kind consisted of pastry of fine flour and oil prepared in different forms. The first was maapheh tannur, oven-baking: by תּנּוּר we are not to understand a baker’s over (Hos 7:4, Hos 7:6), but a large pot in the room, such as are used for baking cakes in the East even to the present day (see my Archäol. §99, 4).
