Numbers 19:18-20

Thomson(i) 18 and a man who is clean shall take hyssop, and dip it in the water, and sprinkle it on the house, and on the vessels, and on the persons who may be in the house, and on him who hath touched a human bone, or a man who hath been slain, or one dead, or a grave. 19 The clean person shall sprinkle it on the unclean, on the third day, and on the seventh day. And on the seventh day he shall purify himself^ and shall wash his clothes, and wash himself with water, and be unclean until evening. 20 And whoever shall be defiled, and not purified, that soul shall be cut off from the congregation, because he hath defiled the holy things of the Lord. Because the water of sprinkling hath not been sprinkled on him, he is unclean.
