Numbers 19:5-7

⁵Another priest must burn the heifer in his sight. He must burn its hide, flesh, and its blood with its dung.

⁶The priest must take cedarwood, hyssop, and scarlet wool, and throw it all into the middle of the burning heifer.

⁷Then he must wash his clothes and bathe in water. Then he may come into the camp, where he will remain unclean until the evening.
