'Rough' 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 did not know;I will guide them on paths they have not known.I will turn darkness to light in front of themand rough places into level ground.This is what I will do for them,and I will not forsake them.

Every valley will be filled,and every mountain and hill will be made low;the crooked will become straight,the rough ways smooth,
