15 For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance-now that he has died as a ransom to set them free from the sins committed under the first covenant. 16 In the case of a will, it is necessary to prove the death of the one who made it, 17 because a will is in force only when somebody has died; it never takes effect while the one who made it is living. 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." 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.
