And almost all things are by the law purged with blood; and without shedding of blood is no remission. And almost all things are - purged with blood - The apostle says almost, because in some cases certain vessels were purified by water, some by fire, Numbers 31:23, and some with the ashes of the red heifer, Numbers 19:2-10, but it was always understood that every thing was at first consecrated by the blood of the victim.
And without shedding of blood is no remission - The apostle shows fully here what is one of his great objects in the whole of this epistle, viz. that there is no salvation but through the sacrificial death of Christ, and to prefigure this the law itself would not grant any remission of sin without the blood of a victim. This is a maxim even among the Jews themselves, אין כפרה אלא בדם ein capparah ella bedam, "There is no expiation but by blood." Yoma, fol. 5, 1; Menachoth, fol. 93, 2. Every sinner has forfeited his life by his transgressions, and the law of God requires his death; the blood of the victim, which is its life, is shed as a substitute for the life of the sinner. By these victims the sacrifice of Christ was typified. He gave his life for the life of the world; human life for human life, but a life infinitely dignified by its union with God.
