Numbers 19, 7 – 10 „The priest shall then wash his garments and bathe his body in water, afterward he may enter the camp. The priest remains unclean until the evening. 8Likewise, the one who burned the heifer shall wash his garments in water, bathe his body in water, and be unclean until evening. 9Then somebody who is clean shall gather up the ashes of the heifer and deposit them in a clean place outside the camp. There they are to be kept to prepare purification water for the Israelite community. This is a purification offering. 10The one who has gathered up the ashes of the heifer shall also wash his garments and be unclean until evening. This is a permanent statute, both for the Israelites and for the alien residing among them”.
