Numbers 19:2–22
“This is the statute of the law that the LORD has commanded: Instruct the Israelites to bring you an unblemished red heifer that has no defect and has never been placed under a yoke. / Give it to Eleazar the priest, and he will have it brought outside the camp and slaughtered in his presence. / 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.
