Numbers 19:18-20

LXX2012(i) 18 And a clean man shall take hyssop, and dip it into the water, and sprinkle it upon the house, and the furniture, and all the souls that are therein, and upon him that touched the human bone, or the slain man, or the corpse, or the tomb. 19 And the clean man shall sprinkle [the water] on the unclean on the third day and on the seventh day, and on the seventh day he shall purify himself; and [the other] shall wash his garments, and bathe himself in water, and shall be unclean until evening. 20 And whatever man shall be defiled and shall not purify himself, that soul shall be cut off from the midst of the congregation, because he has defiled the holy things of the Lord, because the water of sprinkling has not been sprinkled upon him; he is unclean.
