Numbers 19:2-9

2“This is the statute of the law which the Lord has commanded: ‘Tell the Israelites to bring you an unblemished red heifer in which there is no defect and on which a yoke has never been placed.

3You shall give it to Eleazar the priest, and it shall be brought outside the camp and be slaughtered in his presence.

4Next Eleazar the priest shall take some of its blood with his finger and sprinkle some of it toward the front of the Tent of Meeting (tabernacle) seven times.

5Then the heifer shall be burned in his sight; its skin, its flesh, its blood, and its waste, shall be burned (reduced to ash).

6The priest shall take cedar wood and hyssop and scarlet [material] and cast them into the midst of the burning heifer.

7Then the priest shall wash his clothes and bathe his body in water; and afterward come into the camp, but he shall be [ceremonially] unclean until evening.

8The one who burns the heifer shall wash his clothes and bathe his body in water, and shall be unclean until evening.

9Now a man who is [ceremonially] clean shall collect the ashes of the heifer and deposit them outside the camp in a clean place, and the congregation of the Israelites shall keep it for water to remove impurity; it is [to be used for] purification from sin.
