The Dead » Touching of, caused uncleanness
"The person who touches any human corpse will be unclean for seven days.
Anyone in the open field who touches a person who has been killed by the sword or has died, or a human bone, or a grave, will be unclean for seven days.
Anyone who touches a body of a person who has died, and does not purify himself, defiles the tabernacle of the Lord. That person will be cut off from Israel. He remains unclean because the water for impurity has not been sprinkled on him, and his uncleanness is still on him.
