Provision is here made for the poor of God's people, and the pacifying of their consciences under the sense of guilt. Those that were not able to bring a lamb might bring for a sin-offering a pair of turtle-doves or two young pigeons; nay, if any were so extremely poor that they were not able to procure these so often as they would have occasion, they might bring a pottle of fine flour, and this should be accepted. Thus the expense of the sin-offering was brought lower than that of any other offering, to teach us that no man's poverty shall ever be a bar in the way of his pardon. The poorest of all may have atonement made for them, if it be not their own fault. Thus the poor are evangelized; and no man shall say that he had not wherewithal to bear the charges of a journey to heaven. Now,

I.If the sinner brought two doves, one was to be offered for a sin-offering and the other for a burnt-offering, Lev 5:7. Observe, 1. Before he offered the burnt-offering, which was for the honour and praise of God, he must offer the sin-offering, to make atonement. We must first see to it that our peace be made with God, and then we may expect that our services for his glory will be accepted. The sin-offering must make way for the burnt-offering. 2. After the sin-offering, which made atonement, came the burnt-offering, as an acknowledgment of the great mercy of God in appointing and accepting the atonement.

II.If he brought fine flour, a handful of it was to be offered, but without either oil or frankincense (Lev 5:11), not only because this would make it too costly for the poor, for whose comfort this sacrifice was appointed, but because it was a sin-offering, and therefore, to show the loathsomeness of the sin for which it was offered, it must not be made grateful either to the taste by oil or to the smell by frankincense. The unsavouriness of the offering was to intimate that the sinner must never relish his sin again as he had done. God by these sacrifices did speak, 1. Comfort to those that had offended, that they might not despair, nor pine away in their iniquity; but, peace being thus made for them with God, they might have peace in him. 2. Caution likewise not to offend any more, remembering what an expensive troublesome thing it was to make atonement.

Tenth part of an ephah - About three quarts. The ephah contained a little more than seven gallons and a half.

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, Lev 5:1,

and it shall be forgiven him; upon the foot of the atonement made; See Gill on Lev 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, Lev 2:3.

he shall bring his trespass offering unto the Lord for his sins which he hath sinned--A trespass offering differed from a sin offering in the following respects: that it was appointed for persons who had either done evil unwittingly, or were in doubt as to their own criminality; or felt themselves in such a special situation as required sacrifices of that kind [BROWN]. The trespass offering appointed in such cases was a female lamb or kid; if unable to make such an offering, he might bring a pair of turtledoves or two young pigeons--the one to be offered for a sin offering, the other for a burnt offering; or if even that was beyond his ability, the law would be satisfied with the tenth part of an ephah of fine flour without oil or frankincense.
