Hebrews 9:18-21

Goodspeed(i) 18 So even the old agreement could not be ratified without the use of blood. 19 For when Moses had told all the regulations of the Law to all the people, he took calves' and goats' blood, along with water, crimson wool, and a bunch of hyssop, and sprinkled the roll of the Law and all the people, 20 saying, "This blood ratifies the agreement which God has commanded me to make with you." 21 The tent too and all the appliances used in the priestly service he sprinkled with blood in the same way.
