'Rough' in the Bible

My skin is covered with worms and clods of dirt; my skin becomes rough and then breaks out afresh.

Every valley will be lifted up, and every mountain and hill will be lowered; the rough ground will become level, and the mountain ridges made a plain.

I'll help the blind walk, even on a road they do not know; I'll guide them in directions they do not know. I'll turn the dark places into light in front of them, and the rough places into level ground. These are the things I will do, and I won't abandon them.

Furthermore, it will come about at that time that every prophet will become ashamed of his vision as he prophesies. They will wear no rough garments intended to deceive others."
