The Water of Cleansing

19 The LORD said to Moses and Aaron: 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. 3 Give it to Eleazar the priest; it is to be taken outside the camp and slaughtered in his presence. 4 Then 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. 5 While he watches, the heifer is to be burned—its hide, flesh, blood and offal. 6 The priest is to take some cedar wood, hyssop and scarlet wool and throw them onto the burning heifer. 7 After that, the priest must wash his clothes and bathe himself with water. He may then come into the camp, but he will be ceremonially unclean till evening. 8 The man who burns it must also wash his clothes and bathe with water, and he too will be unclean till evening.
9 “A man who is clean shall gather up the ashes of the heifer and put them in a ceremonially clean place outside the camp. They shall be kept by the Israelite community for use in the water of cleansing; it is for purification from sin. 10 The man who gathers up the ashes of the heifer must also wash his clothes, and he too will be unclean till evening. This will be a lasting ordinance both for the Israelites and for the aliens living among them. (Numbers 19:1-10)
