Numbers 19:19-21

Leeser(i) 19 And the clean person shall sprinkle upon the unclean on the third day and on the seventh day; and when he hath purified him on the seventh day, then shall he wash his clothes, and bathe himself in water, and shall be clean at evening. 20 But a man that is unclean, and doth not purify himself, that soul shall be cut off from among the congregation; because the sanctuary of the Lord hath he defiled; the water of sprinkling hath not been sprinkled upon him; he is unclean. 21 And it shall be unto them for a perpetual statute; and he that sprinkleth the water of sprinkling shall wash his clothes; and he that toucheth the water of sprinkling shall be unclean until the evening.
