Numbers 19:3-6

³And thou shalt give her to Eleazar the priest; and they shall bring her out of the camp into a clean place, and shall kill her before his face.

⁴And Eleazar shall take of her blood, and sprinkle of her blood seven times in front of the tabernacle of witness.

⁵And they shall burn her to ashes before him; and her skin and her flesh and her blood, with her dung, shall be consumed.

⁶And the priest shall take cedar wood and hyssop and scarlet wool, and they shall cast them into the midst of the burning of the heifer.
