Then shall he bring it to the priest
 The flour just as it was, not kneaded and made into a cake, as appears by what follows: 
 and the priest shall take his handful of it;
 as much of the flour as he could hold in one hand: 
 [even] a memorial thereof;
 to bring to mind his sin, and the goodness of God in admitting of an offering for it, and forgiving it upon that: 
 and burn [it] on the altar, according to the offerings made by fire
 unto the Lord;
 in the same manner as other burnt offerings were made: 
 it [is] a sin [offering];
 or an expiatory sacrifice for sin.
