Numbers 19:13-16

¹³Whosoever toucheth the dead body, the person of any man that is dead, and purifieth himself not, hath defiled the tabernacle of the Lord; and that soul shall be cut off from Israel; because the water of sprinkling 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, on which there is not a closely fitting cover, is unclean.

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