'Bone' in the Bible

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.

A person who is clean is to take hyssop, dip it in the water, and sprinkle the tent, all the furnishings, and the people who were there. He is also to sprinkle the one who touched a bone, a grave, a corpse, or a person who had been killed.
