iuxta hunc ritum aspergantur aqua lustrationis et radant omnes pilos carnis suae cumque laverint vestimenta sua et mundati fuerin
and thus shalt thou do unto them, to cleanse them: sprinkle water of purifying upon them, and let them shave all their flesh, and let them wash their clothes, and so make themselves clean.

si quis hoc ritu non fuerit expiatus peribit anima illius de medio ecclesiae quia sanctuarium domini polluit et non est aqua lustrationis aspersu
but the man that shall be unclean, and shall not purify himself, that soul shall be cut off from among the congregation, because he hath defiled the sanctuary of the lord: the water of separation hath not been sprinkled upon him; he is unclean.
