1 Samuel 13:6-7
13:6 The men of Israel realized they had a problem because their army was hard pressed. So the army hid in caves, thickets, cliffs, strongholds, and cisterns.
13:7 Some of the Hebrews crossed over the Jordan River to the land of Gad and Gilead. But Saul stayed at Gilgal; the entire army that was with him was terrified.
