Bamidbar 19:18-20 Orthodox Jewish Bible (OJB)
18 And an ish tahor shall take hyssop, and dip it in the mayim, and sprinkle it upon the ohel, and upon all the vessels, and upon the nefashot that were there, and upon him that touched a bone, or one slain, or one dead, or a kever;
19 And the tahor (clean person) shall sprinkle upon the tamei on the Yom HaShelishi, and on the seventh day; and on the seventh day he shall make himself tahor, and wash his clothes, and immerse himself in mayim, and shall be tahor at erev [T.N. On the messianic mikveh see Co 2:11-12].
20 But the man that shall be tamei, and shall not purify himself, that nefesh shall be cut off from among the Kahal, because he hath contaminated the Mikdash Hashem; the water of sprinkling hath not been sprinkled upon him; he is tamei.
