Numbers 19:14-16

Amplified Bible

¹⁴ ‘This is the law when a man dies in a tent: everyone who comes into the tent and everyone who is in the tent shall be [ceremonially] unclean for seven days. ¹⁵ Every open container [in the tent], which has no covering tied down on it, is unclean. ¹⁶ Also, anyone in the open field who touches one who has been killed with a sword or who has died [of natural causes], or a human bone or a grave, shall be unclean for seven days.
