'Rough' in the Bible

“Let every valley be lifted up,And every mountain and hill be made low;And let the rough ground become a plain,And the rugged terrain a broad valley;

“I will go before you and make the rough places smooth;I will shatter the doors of bronze and cut through their iron bars.

‘Every ravine will be filled,And every mountain and hill will be brought low;The crooked will become straight,And the rough roads smooth;
