The Lord spoke to Moses and Aaron, saying:
This is a statute of the law that the Lord has commanded: Tell the Israelites to bring you a red heifer without defect, in which there is no blemish and on which no yoke has been laid.
You shall give it to the priest Eleazar, and it shall be taken outside the camp and slaughtered in his presence.
The priest Eleazar shall take some of its blood with his finger and sprinkle it seven times towards the front of the tent of meeting.
Then the heifer shall be burned in his sight; its skin, its flesh, and its blood, with its dung, shall be burned.
The priest shall take cedarwood, hyssop, and crimson material, and throw them into the fire in which the heifer is burning.
Then the priest shall wash his clothes and bathe his body in water, and afterwards he may come into the camp; but the priest shall remain unclean until evening.
The one who burns the heifer shall wash his clothes in water and bathe his body in water; he shall remain unclean until evening.
