Numbers 19:2-6

2“This is a requirement of the law that the Lord has commanded: Tell the Israelites to bring you a red heifer without defect or blemish and that has never been under a yoke.

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

4Then Eleazar the priest is to take some of its blood on his finger and sprinkle it seven times toward the front of the tent of meeting.

5While he watches, the heifer is to be burned—its hide, flesh, blood and intestines.

6The priest is to take some cedar wood, hyssop and scarlet wool and throw them onto the burning heifer.
