'Mountains' in the Bible

Every valley will be lifted up, and all the mountains and hills made low, and the twisted will be made straight, and the rough ways smooth;

Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.

Then shall they begin to say to the mountains, Fall on us; and to the hills, Cover us.
