Numbers 19:2-9

2“This is the ordinance of the law which the Lord has commanded: ‘Instruct the Israelites to bring you a red heifer without blemish, which has no defect and has never carried a yoke.

3You must give it to Eleazar the priest so that he can take it outside the camp, and it must be slaughtered before him.

4Eleazar the priest is to take some of its blood with his finger, and sprinkle some of the blood seven times directly in front of the tent of meeting.

5Then the heifer must be burned in his sight – its skin, its flesh, its blood, and its offal is to be burned.

6And the priest must take cedar wood, hyssop, and scarlet wool and throw them into the midst of the fire where the heifer is burning.

7Then the priest must wash his clothes and bathe himself in water, and afterward he may come into the camp, but the priest will be ceremonially unclean until evening.

8The one who burns it must wash his clothes in water and bathe himself in water. He will be ceremonially unclean until evening.

9“‘Then a man who is ceremonially clean must gather up the ashes of the red heifer and put them in a ceremonially clean place outside the camp. They must be kept for the community of the Israelites for use in the water of purification – it is a purification for sin.
