MSB(i) 14 This is the law when a person dies in a tent: Everyone who enters the tent and everyone already in the tent will be unclean for seven days, 15 and any open container without a lid fastened on it is unclean. 16 Anyone in the open field who touches someone who has been killed by the sword or has died of natural causes, or anyone who touches a human bone or a grave, will be unclean for seven days.
