Numbers 19:1-6

The LORD said to Moses and Aaron, “These are the teachings that the LORD commanded. Tell the Israelites to get a young red cow that does not have anything wrong with it and that has never been worked. Give the cow to Eleazar the priest; he will take it outside the camp and kill it. Then Eleazar the priest must put some of its blood on his finger and sprinkle it seven times toward the front of the Meeting Tent. The whole cow must be burned while he watches; the skin, the meat, the blood, and the intestines must all be burned. Then the priest must take a cedar stick, a hyssop branch, and a red string and throw them onto the burning cow.
