Numbers 19:18-20

New King James Version

¹⁸ A clean person shall take ^(A)hyssop and dip it in the water, sprinkle it on the tent, on all the vessels, on the persons who were there, or on the one who touched a bone, the slain, the dead, or a grave. ¹⁹ The clean person shall sprinkle the unclean on the third day and on the seventh day; ^(B)and on the seventh day he shall purify himself, wash his clothes, and bathe in water; and at evening he shall be clean.

²⁰ ‘But the man who is unclean and does not purify himself, that person shall be cut off from among the assembly, because he has ^(C)defiled the sanctuary of the Lord. The water of purification has not been sprinkled on him; he is unclean.
