NUMBERS 19:13-16

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: every one that cometh into the tent, and every one 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 in the open field toucheth one that is slain with a sword, or a dead body, or a bone of a man, or a grave, shall be unclean seven days.
