Numbers 19:3-6

³Hand it over to Eleazar the priest, and he will take it outside the camp and have it slaughtered before him.

⁴Eleazar the priest will put some of its blood on his finger and sprinkle it seven times towards the entrance of the Tent of Meeting.

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.
