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.

But shall not divide it - See Clarke's note on Lev 1:16.

And he shall bring them unto the priest,.... Either two turtledoves, or two young pigeons:

who shall offer that which is for the sin offering first; that which is chosen for it, as the Targum of Jonathan; and this choice was made, not by the priest, but by the man that brought the offering, who separated it, and said, lo, this is a sin offering, and after that said, lo, this is a burnt offering (a); the sin offering was offered first, which was to make atonement for sin, and then the burnt offering, to denote the divine acceptance of it; and so Ben Gersom observes, it was proper to offer the sin offering first, to atone for his sin, that after he (God) was appeased this way, he might receive his gift; for the burnt offering was as a gift. Jarchi compares it to an advocate, who first goes in to appease, and when he has appeased, the gift goes in after him:

and wring off his head from his neck, but shall not divide it asunder: be it a turtledove or a young pigeon, so it was to be served; the head was not to be separated from the body, but was nipped by the nail of the priest "in" the neck, as it might be rendered (b); over against the neck, as the Targums of Onkelos and Jonathan render it; the hinder part, or what is behind the throat, as Jarchi and Ben Molech interpret it; so that the part which was nipped was the neck; and this nip was made so large, as that the blood was let out by it, as appears from the following verse Lev 5:9, and yet the head was not divided from the body; the head hung by a piece of skin on the back part; of the manner of performing this, and the mystery of it; see Gill on Lev 1:15.

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.
