CLV(i)
18 A clean man will take hyssop, dip it in the water and spatter it on the tent and on all the vessels and on the souls which are there and on the one touching a bone or one wounded to death or a dead body or a tomb.
19 The clean one will spatter on the unclean on the third day and on the seventh day and thus expiate him on the seventh day. He will then rinse his garments and bathe in water and will be clean in the evening.
