Numbers 19:5 MSG

[5] “Then under Eleazar’s supervision burn the cow, the whole thing—hide, meat, blood, even its dung. The priest then will take a stick of cedar, some sprigs of hyssop, and a piece of scarlet material and throw them on the burning cow. Afterwards the priest must wash his clothes and bathe well with water. He can then come into the camp but he remains ritually unclean until evening. The man who burns the cow must also wash his clothes and bathe with water. He also is unclean until evening.
