And the priest shall make an atonement for him
By burning the handful of flour brought by him, as an emblem of the painful sufferings of Christ, whereby he made atonement for the sins of his people:
as touching his sin that he hath sinned in one of these;
for whatsoever sin he had committed in any of the above cases, ( Leviticus 5:1-4 ) :
and it shall be forgiven him;
upon the foot of the atonement made; (See Gill on Leviticus 5:10):
and [the remnant] shall be the priest's as a meat offering;
the whole tenth part of an ephah of fine flour was the priest's, excepting the handful he took and burnt, just as in the case of a common meat offering, ( Leviticus 2:3 ) .
