The Lord said to Moses, “Speak to the priests, the sons of Aaron, and say to them: ‘A priest must not make himself ceremonially unclean for any of his people who die,
“ ‘A priest must not defile himself by going near a dead person; however, if the dead person was his father or mother, son or daughter, brother or unmarried sister, then he may defile himself.
“Hear this, you priests! Pay attention, you Israelites! Listen, royal house! This judgment is against you: You have been a snare at Mizpah, a net spread out on Tabor.
“Anyone out in the open who touches someone who has been killed with a sword or someone who has died a natural death, or anyone who touches a human bone or a grave, will be unclean for seven days.
“Command the Israelites to send away from the camp anyone who has a defiling skin disease or a discharge of any kind, or who is ceremonially unclean because of a dead body.
