Numbers 19:20-21

CLV(i) 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. 21 It will be to them an eonian statute that the one spattering the water of impurity shall also rinse his garments, and the one touching the water of impurity shall be unclean until the evening.
