'Level' in the Bible

The way of the righteous [those in right-standing with God—living in moral and spiritual integrity] is smooth and level;O Upright One, make a level path for the just and righteous.

“Every valley shall be raised,And every mountain and hill be made low;And let the rough ground become a plain,And the rugged places a broad valley.

“I will go before you and level the mountains;I will shatter the doors of bronze and cut through the bars of iron.
