1 Samuel 13:6

When the men of Israel saw that they were in a strait, in a most difficult and dangerous position, (for the people were distressed, oppressed by the enemy, who robbed and plundered as they chose,) then the people did hide themselves in caves, and in thickets, secluded places in thorny undergrowth, and in rocks, in clefts and caves of the hills, and in high places, strongly built towers in lonely situations, and in pits.
