Numbers 19:20-22

New Revised Standard Version Catholic Edition

²⁰ Any who are unclean but do not purify themselves, those persons shall be cut off from the assembly, for they have defiled the sanctuary of the Lord. Since the water for cleansing has not been dashed on them, they are unclean.

²¹ It shall be a perpetual statute for them. The one who sprinkles the water for cleansing shall wash his clothes, and whoever touches the water for cleansing shall be unclean until evening. ²² Whatever the unclean person touches shall be unclean, and anyone who touches it shall be unclean until evening.
