7:1-10 In the sin-offering and the trespass-offering, the sacrifice was divided between the altar and the priest; the offerer had no share, as he had in the peace-offerings. The former expressed repentance and sorrow for sin, therefore it was more proper to fast than feast; the peace-offerings denoted communion with a reconciled God in Christ, the joy and gratitude of a pardoned sinner, and the privileges of a true believer.

8. the priest shall have to himself the skin of the burnt offering which he hath offered—All the flesh and the fat of the burnt offerings being consumed, nothing remained to the priest but the skin. It has been thought that this was a patriarchal usage, incorporated with the Mosaic law, and that the right of the sacrificer to the skin of the victim was transmitted from the example of Adam (see on [37]Ge 3:21).
