Numbers 19:18-20

International Standard Version

¹⁸ A clean person is to take some hyssop, dip it in water, and then sprinkle it on the tent, on every vessel, and on whoever^[a] was there (that is, on whoever touched the bones, the killed person, or the dead body, including whoever dug the grave). ¹⁹ The clean person is to sprinkle the unclean person on the third day and seventh day and then he is to purify himself on the seventh day, wash his clothes, and bathe with water. He is to be considered clean at evening.

²⁰ “The person^[b] who is unclean but who doesn’t purify himself is to be eliminated from contact with the assembly, since he has defiled the Lord’s sanctuary and the water of impurity wasn’t sprinkled on him. He is to be considered unclean
