Matthew Poole and continuators on Leviticus 5:13

13 And the Priest shall make an atonement for him as touching his sin, that he hath sinned in one of these, and it shall be forgiven him: and the remnant shall be the priests, as a meat-offering .

As it was in the meat-offering, where all except one handful fell to the share of the Priests. See Lev. 2. 3. and 7. 9. And is this the rather mentioned here, because in the foregoing sacrifices, Levit. 4. 3, &c. 13, &c. the Priest had no part reserved for him.
