Numbers 19:2-6

19:2 “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. 19:3 You must give it to Eleazar the priest so that he can take it outside the camp, and it must be slaughtered before him. 19:4 Eleazar 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. 19:5 Then the heifer must be burned in his sight – its skin, its flesh, its blood, and its offal is to be burned. 19:6 And the priest must take cedar wood, hyssop, and scarlet wool and throw them into the midst of the fire where the heifer is burning.
