'Defile the Land' in the Bible

If you defile the land, it will vomit you out as it has vomited out the nations that were before you.

“Do not defile the land where you are, for bloodshed defiles the land, and there can be no atonement for the land because of the blood that is shed on it, except by the blood of the person who shed it.

you are not to leave his corpse on the tree overnight but are to bury him that day, for anyone hung on a tree is under God’s curse. You must not defile the land the Lord your God is giving you as an inheritance.
