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.

they may not leave any of it until morning or break any of its bones. They must observe the Passover according to all its statutes.

God brought him out of Egypt;
He is like the horns of a wild ox for them.
He will feed on enemy nations
and gnaw their bones;
he will strike them with his arrows.
