9:18 {12} Whereupon neither the first [testament] was dedicated without blood.
(12) There must be a proportion between those things which purify and those which are purified: Under the law all those figures were earthly, the tabernacle, the book, the vessels, the sacrifices, although they were the signs of heavenly things. Therefore it was required that all those should be purified with some matter and ceremony of the same nature, that is, with the blood of beasts, with water, wool, hyssop. But under Christ all things are heavenly, a heavenly tabernacle, heavenly sacrifice, heavenly people, heavenly doctrine, and heaven itself is set open before us for an eternal home. Therefore all these things are sanctified in a similar way, that is, with the everlasting offering of the quickening blood of Christ.
9:18 Neither the first [testament] was dedicated without blood. The death and shedding of the blood of Christ was necessary to the inauguration of the New Testament, as has just been shown. Even when the First was inaugurated, Christ died in type and blood was shed. I believe that the apostle means to say that even in the inauguration of the Old Testament death was necessary, the death of a victim, which pointed to Christ's death.
9:18 Whence neither was the first - The Jewish covenant, originally transacted without the blood of an appointed sacrifice.
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.
