Numbers 19:18-20 Evangelical Heritage Version (EHV)
18 A ceremonially clean person is to take hyssop, dip it in the water, and sprinkle the water on the tent, on all the items, and on the people who were there. He is also to sprinkle it on anyone who has touched someone who was killed or someone who has died and on anyone who has touched a grave or a human bone. 19 The ceremonially clean person will sprinkle the unclean person on the third day and on the seventh day. On the seventh day, after the ceremonially clean person has purified the unclean person, that person will wash his clothes and bathe himself in water, and he will be clean at evening. 20 But anyone who is unclean and refuses to purify himself will be cut off from the midst of the assembly, because he has defiled the sanctuary of the Lord. The water for removing impurity was not sprinkled on him, so he remains unclean.
