Numbers 19:19-21

International Standard Version

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^[a] 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 ²¹ as a continuing^[b] reminder to them. Whoever sprinkles the water of impurity is to wash his clothes, and whoever comes in contact with the water of impurity is to remain unclean until evening.
