9:22 And almost all things are by the law purged with blood. See Le 16:16,19,33. Under the law almost every thing was purified by blood, lest it had been defiled.
Without shedding of blood is no remission. Every sin under the law required atonement, and no atonement could be made without blood.
9:22 And almost all things - For some were purified by water or fire. Are according to the law purified with blood - Offered or sprinkled. And according to the law, there is no forgiveness of sins without shedding of blood - All this pointed to the blood of Christ effectually cleansing from all sin, and intimated, there can be no purification from it by any other means.
9:15-22 The solemn transactions between God and man, are sometimes called a covenant, here a testament, which is a willing deed of a person, bestowing legacies on such persons as are described, and it only takes effect upon his death. Thus Christ died, not only to obtain the blessings of salvation for us, but to give power to the disposal of them. All, by sin, were become guilty before God, had forfeited every thing that is good; but God, willing to show the greatness of his mercy, proclaimed a covenant of grace. Nothing could be clean to a sinner, not even his religious duties; except as his guilt was done away by the death of a sacrifice, of value sufficient for that end, and unless he continually depended upon it. May we ascribe all real good works to the same all-procuring cause, and offer our spiritual sacrifices as sprinkled with Christ's blood, and so purified from their defilement.
