Numbers 19:19-21

New American Standard Bible

¹⁹ Then the clean person ^(A)shall sprinkle on the unclean on the third day and on the seventh day; and on the seventh day he shall purify him, and he shall wash his clothes and bathe himself in water and will be clean by evening.

²⁰ ‘But the person who is unclean and does not purify himself, that person shall be cut off from the midst of the assembly, because he has ^(B)defiled the sanctuary of the Lord; the water for impurity has not been sprinkled on him, so he is unclean. ²¹ So it shall be a permanent statute for them. And the one ^(C)who sprinkles the water for impurity shall wash his clothes, and the one who touches the water for impurity will be unclean until evening.
