18 This is why even the first covenant was not put into effect without blood. 19 When Moses had proclaimed every command of the law to all the people, he took the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people. 20 He said, "This is the blood of the covenant, which God has commanded you to keep."[1] 21 In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies. 22 In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.
18 Whereupon neither the first testament was dedicated
18 Therefore not even the first covenant was inaugurated without blood. 19 For when every commandment of the law had been declared by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, 20 saying, "This is the blood of the covenant that God commanded for you." 21 And in the same way he sprinkled with the blood both the tent and all the vessels used in worship. 22 Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
18 Even the first plan required a death to set it in motion. 19 After Moses had read out all the terms of the plan of the law - God's "will" - he took the blood of sacrificed animals and, in a solemn ritual, sprinkled the document and the people who were its beneficiaries. 20 And then he attested its validity with the words, "This is the blood of the covenant commanded by God." 21 He did the same thing with the place of worship and its furniture. 22 Moses said to the people, "This is the blood of the covenant God has established with you." Practically everything in a will hinges on a death. That's why blood, the evidence of death, is used so much in our tradition, especially regarding forgiveness of sins.
18 Therefore not even the first covenant was dedicated without blood. 19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and goats, with water, scarlet wool, and hyssop, and sprinkled both the book itself and all the people, 20 saying, "This is the blood of the covenant which God has commanded you." 21 Then likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry. 22 And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.
18 That is why even the first covenant was put into effect with the blood of an animal. 19 For after Moses had read each of God's commandments to all the people, he took the blood of calves and goats, along with water, and sprinkled both the book of God's law and all the people, using hyssop branches and scarlet wool. 20 Then he said, "This blood confirms the covenant God has made with you." 21 And in the same way, he sprinkled blood on the Tabernacle and on everything used for worship. 22 In fact, according to the law of Moses, nearly everything was purified with blood. For without the shedding of blood, there is no forgiveness.
Matthew Henry's Commentary on Hebrews 9:18-22
Commentary on Hebrews 9:15-22
(Read Hebrews 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.
