1 Samuel 13:6

They were in a strait, notwithstanding their former presumption, that if they had a king they should be free from all such straits. And hereby God intended to teach them the vanity of all carnal confidence in men; and that they did not one jot less need the help and favour of God now than they did before, when they had no king. The people were distressed; they were not mistaken in their apprehensions of danger, as men oft are, for they were really in great danger, their enemy's host far exceeding theirs, both in number, and order, and courage, and arms. The people did hide themselves in caves; whereof there were divers in those parts for this very use, as we read in Josephus, and in the Holy Scripture.
