Numbers 19:12

8And he that burneth her shall wash his clothes in water, and bathe his flesh in water, and shall be unclean until the even.

9And 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.

10And 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.

11He that toucheth the dead body of any man shall be unclean seven days.

12He 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.

13Whosoever 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.

14This is the law, when a man dieth in a tent: all that come into the tent, and all that is in the tent, shall be unclean seven days.

15And every open vessel, which hath no covering bound upon it, is unclean.

16And whosoever toucheth one that is slain with a sword in the open fields, or a dead body, or a bone of a man, or a grave, shall be unclean seven days.
