The Lord said to Moses, ‘Speak to Aaron’s sons, the priests, and tell them: A priest is not to make himself ceremonially unclean for a dead person among his relatives,
A priest may not come near a dead person so that he becomes defiled. However, he may defile himself for a father, a mother, a son, a daughter, a brother, or an unmarried sister.
Hear this, priests! Pay attention, house of Israel! Listen, royal house! For the judgement applies to you because you have been a snare at Mizpah and a net spread out on Tabor.
Anyone in the open field who touches a person who has been killed by the sword or has died, or who even touches a human bone, or a grave, will be unclean for seven days.
‘Command the Israelites to send away anyone from the camp who is afflicted with a skin disease, anyone who has a discharge, or anyone who is defiled because of a corpse.
