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.
