Numbers 19:18-20 New Life Version (NLV)
18 Then a clean person must take hyssop and put it in the water, and put it on the tent and on all the objects within the tent. He must put it on the persons who were there, and on the one who touched the bone or the man who was killed or the dead person or the grave. 19 The clean person must put the water on whoever is unclean, on the third day and on the seventh day. He will make him clean on the seventh day. He will wash his clothes and wash himself in water, and will be clean at evening.
20 “But the man who is unclean and does not make himself clean, will no longer be one of God’s people. Because he has made unclean the holy place of the Lord. The water for cleaning has not been put on him. He is unclean.
