Numbers 19:12

9 And a man [that is] clean shall gather the ashes of the heifer, and lay [them] 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 evening: and it shall be to the children of Israel, and to 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 shall not purify himself the third day, then the seventh day he shall not be clean.

13 Whoever 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.

14 This [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.

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