John Gill Commentary Leviticus 2:10

"And that which is left of the meal-offering shall be Aaron`s and his sons`: it is a thing most holy of the offerings of Jehovah made by fire." — Leviticus 2:10 (ASV)

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 Leviticus 2:3).
