Numbers 19:20-21

DouayRheims(i) 20 If any man be not expiated after this rite, his soul shall perish out of the midst of the church: because he hath profaned the sanctuary of the Lord, and was not sprinkled with the water of purification. 21 This precept shall be an ordinance for ever. He also that sprinkled the water, shall wash his garments. Every one that shall touch the waters of expiation, shall be unclean until the evening.
