Numbers 19:3-6

³And you shall deliver her to Eleazar the priest, who shall bring her forth without the camp, and shall immolate her in the sight of all:

⁴And dipping his finger in her blood, shall sprinkle it over against the door of the tabernacle seven times,

⁵And shall burn her in the sight of all, delivering up to the fire her skin, and her flesh, and her blood, and her dung.

⁶The priest shall also take cedar wood, and hyssop, and scarlet twice dyed, and cast it into the flame, with which the cow is consumed.
