'Rocks' in the Bible

Every city flees for the noise of the horsemen and archers; they go into the thickets, and climb up on the rocks: every city is forsaken, and not a man dwells therein.

Behold, I will send for many fishermen, says Yahweh, 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 you, destroying mountain, says Yahweh, which destroys all the earth; and I will stretch out my hand on you, and roll you down from the rocks, and will make you a burnt mountain.
