Numbers 19:1-13   1. And the LORD spake unto Moses and unto Aaron, saying, 2. This is the ordinance of the law which the LORD hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke: 3. And ye shall give her unto Eleazar the priest, that he may bring her forth without the camp, and one shall slay her before his face: 4. And Eleazar the priest shall take of her blood with his finger, and sprinkle of her blood directly before the tabernacle of the congregation seven times: 5. And one shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn: 6. And the priest shall take cedar wood, and hyssop, and scarlet, and cast it into the midst of the burning of the heifer. 7. Then the priest shall wash his clothes, and he shall bathe his flesh in water, and afterward he shall come into the camp, and the priest shall be unclean until the even. 8. And he that burneth her shall wash his clothes in water, and bathe his flesh in water, and shall be unclean until the even. 9. And a man that is clean shall gather up the ashes of the heifer, and lay them up without the camp in a clean place, and it shall be kept for the congregation of the children of Israel for a water of separation: it is a purification for sin. 10. And he that gathereth the ashes of the heifer shall wash his clothes, and be unclean until the even: and it shall be unto the children of Israel, and unto the stranger that sojourneth among them, for a statute for ever. 11. ¶He that toucheth the dead body of any man shall be unclean seven days. 12. He shall purify himself with it on the third day, and on the seventh day he shall be clean: but if he purify not himself the third day, then the seventh day he shall not be clean. 13. Whosoever toucheth the dead body of any man that is dead, and purifieth not himself, defileth the tabernacle of the LORD; and that soul shall be cut off from Israel: because the water of separation was not sprinkled upon him, he shall be unclean; his uncleanness is yet upon him.

Numbers 8:6-19   6. Take the Levites from among the children of Israel, and cleanse them. 7. And thus shalt thou do unto them, to cleanse them: Sprinkle water of purifying upon them, and let them shave all their flesh, and let them wash their clothes, and so make themselves clean. 8. Then let them take a young bullock with his meat offering, even fine flour mingled with oil, and another young bullock shalt thou take for a sin offering. 9. And thou shalt bring the Levites before the tabernacle of the congregation: and thou shalt gather the whole assembly of the children of Israel together: 10. And thou shalt bring the Levites before the LORD: and the children of Israel shall put their hands upon the Levites: 11. And Aaron shall offer the Levites before the LORD for an offering of the children of Israel, that they may execute the service of the LORD. 12. And the Levites shall lay their hands upon the heads of the bullocks: and thou shalt offer the one for a sin offering, and the other for a burnt offering, unto the LORD, to make an atonement for the Levites. 13. And thou shalt set the Levites before Aaron, and before his sons, and offer them for an offering unto the LORD. 14. Thus shalt thou separate the Levites from among the children of Israel: and the Levites shall be mine. 15. And after that shall the Levites go in to do the service of the tabernacle of the congregation: and thou shalt cleanse them, and offer them for an offering. 16. For they are wholly given unto me from among the children of Israel; instead of such as open every womb, even instead of the firstborn of all the children of Israel, have I taken them unto me. 17. For all the firstborn of the children of Israel are mine, both man and beast: on the day that I smote every firstborn in the land of Egypt I sanctified them for myself. 18. And I have taken the Levites for all the firstborn of the children of Israel. 19. And I have given the Levites as a gift to Aaron and to his sons from among the children of Israel, to do the service of the children of Israel in the tabernacle of the congregation, and to make an atonement for the children of Israel: that there be no plague among the children of Israel, when the children of Israel come nigh unto the sanctuary.
