'Permanent' in the Bible

Keep his statutes and commandments that I am setting forth today so that it may go well with you and your descendants and that you may enjoy longevity in the land that the Lord your God is about to give you as a permanent possession.

Gather whatever you've taken as spoils at the public square of the town, then burn the town, along with whatever you've taken, as an offering to the LORD your God. It will remain a permanent mound of ruins, never to be rebuilt again.
