  17 H2931 And for the unclean H3947 they shall take H6083 of the ashes H8316 of the burning H2403 of the sin-offering; H2416 and running H4325 water H5414 shall be put H3627 thereto in a vessel:
  18 H2889 and a clean H376 person H3947 shall take H231 hyssop, H2881 and dip H4325 it in the water, H5137 and sprinkle H168 it upon the tent, H3627 and upon all the vessels, H5315 and upon the persons H5060 that were there, and upon him that touched H6106 the bone, H2491 or the slain, H4191 or the dead, H6913 or the grave:
  19 H2889 and the clean H5137 person shall sprinkle H2931 upon the unclean H7992 on the third H3117 day, H7637 and on the seventh H3117 day: H7637 and on the seventh H3117 day H2398 he shall purify H3526 him; and he shall wash H899 his clothes, H3526 and bathe H4325 himself in water, H2891 and shall be clean H6153 at even.
