Numbers 19:1-6

Now the LORD spoke to Moses and Aaron, saying, “This is the ordinance of the law which the LORD has commanded, saying: ‘Speak to the children of Israel, that they bring you a red heifer without blemish, in which there is no defect and on which a yoke has never come. You shall give it to Eleazar the priest, that he may take it outside the camp, and it shall be slaughtered before him; and Eleazar the priest shall take some of its blood with his finger, and sprinkle some of its blood seven times directly in front of the tabernacle of meeting. Then the heifer shall be burned in his sight: its hide, its flesh, its blood, and its offal shall be burned. And the priest shall take cedar wood and hyssop and scarlet, and cast them into the midst of the fire burning the heifer.
