CLV(i)
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.
20 If anyone who is unclean does not purify himself from sin, then that soul will be cut off from the midst of the assembly, for the sanctuary of Yahweh has he defiled; water of impurity was not sprinkled on him, he is unclean.
