the body must not remain hanging from the tree overnight. You must bury the body that same day, for anyone who is hung is cursed in the sight of God. In this way, you will prevent the defilement of the land the Lord your God is giving you as your special possession.
And if someone in an open field touches the corpse of someone who was killed with a sword or who died a natural death, or if someone touches a human bone or a grave, that person will be defiled for seven days.
