21 And it shall be a perpetual statute for them. He who sprinkles the water for impurity shall wash his clothes; and he who touches the water for impurity shall be unclean until evening.

Numbers 19:21 In-Context

19 and the clean person shall sprinkle upon the unclean on the third day and on the seventh day; thus on the seventh day he shall cleanse him, and he shall wash his clothes and bathe himself in water, and at evening he shall be clean.
20 "But the man who is unclean and does not cleanse himself, that person shall be cut off from the midst of the assembly, since he has defiled the sanctuary of the LORD; because the water for impurity has not been thrown upon him, he is unclean.
21 And it shall be a perpetual statute for them. He who sprinkles the water for impurity shall wash his clothes; and he who touches the water for impurity shall be unclean until evening.
22 And whatever the unclean person touches shall be unclean; and any one who touches it shall be unclean until evening."
