Numbers 19:5-7

⁵Then the cow must be burned as he watches All of it is to be burned—its skin, meat, and blood, as well as its excrement.

⁶The priest shall throw cedar wood, hyssop, and crimson thread on the burning cow.

⁷Then the priest shall wash his clothes and his body in water, and after that he may enter the camp, but he will remain unclean until the evening.
