'Uneven' in the Bible

Every valley will be lifted up,and every mountain and hill will be leveled;the uneven ground will become smoothand the rough places, a plain.

“I will lead the blind by a way they do not know;I will guide them in paths that they do not know.I will make darkness into light before themAnd rugged places into plains.These things I will do [for them],And I will not leave them abandoned or undone.”

“I will go before youand level the uneven places;I will shatter the bronze doorsand cut the iron bars in two.
