Numbers 19:11-14

¹¹He that toucheth a dead person, any dead body of a 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.

¹³Whoever toucheth a dead person, the dead body of a man that is dead, and purifieth not himself, defileth the tabernacle of Jehovah; and that soul shall be cut off from Israel; for 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: every one that cometh into the tent, and all that is in the tent, shall be unclean seven days.
