Numbers 19:13-16

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.

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

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