'Mountains' in the Bible

Now between the narrow roads over the mountains by which Jonathan was making his way to the Philistines' forces, there was a sharp overhanging rock on one side, and a sharp rock on the other side: one was named Bozez and the other Seneh.

Then do not let my blood be drained out on the earth away from the face of the Lord: for the king of Israel has come out to take my life, like one going after birds in the mountains.
