'Rocks' in the Bible

Every city fleeth for the noise of the horsemen and bowmen; they go into the thickets, and climb up upon the rocks: every city is forsaken, and not a man dwelleth therein.

Behold, I will send for many fishers, saith Jehovah, and they shall fish them up; and afterward I will send for many hunters, and they shall hunt them from every mountain, and from every hill, and out of the clefts of the rocks.

Behold, I am against thee, O destroying mountain, saith Jehovah, which destroyest all the earth; and I will stretch out my hand upon thee, and roll thee down from the rocks, and will make thee a burnt mountain.
