Numbers 19:2-9

2“Here is another legal requirement commanded by the Lord: Tell the people of Israel to bring you a red heifer, a perfect animal that has no defects and has never been yoked to a plow.

3Give it to Eleazar the priest, and it will be taken outside the camp and slaughtered in his presence.

4Eleazar will take some of its blood on his finger and sprinkle it seven times toward the front of the Tabernacle.

5As Eleazar watches, the heifer must be burned—its hide, meat, blood, and dung.

6Eleazar the priest must then take a stick of cedar, a hyssop branch, and some scarlet yarn and throw them into the fire where the heifer is burning.

7“Then the priest must wash his clothes and bathe himself in water. Afterward he may return to the camp, though he will remain ceremonially unclean until evening.

8The man who burns the animal must also wash his clothes and bathe himself in water, and he, too, will remain unclean until evening.

9Then someone who is ceremonially clean will gather up the ashes of the heifer and deposit them in a purified place outside the camp. They will be kept there for the community of Israel to use in the water for the purification ceremony. This ceremony is performed for the removal of sin.
