'Perpetual' in the Bible

"You don't fear me, do you?' declares the LORD. "You don't tremble before me, do you? I'm the one who put the sand as a boundary for the sea, a perpetual barrier that it cannot cross. Though the waves toss, they cannot prevail against it, though they roar, they cannot cross it.'

Indeed, I've sworn by myself," declares the LORD, "that Bozrah will become an object of horror and scorn, a waste, and an object of ridicule. All her towns will become perpetual ruins."

"Hazor will become a dwelling place for jackals, a perpetual wasteland. No one will live there; no human being will reside in it."
