1 Samuel 13:2

13:2 Saul selected for himself three thousand men from Israel. Two thousand of these were with Saul at Micmash and in the hill country of Bethel; the remaining thousand were with Jonathan at Gibeah in the territory of Benjamin. He sent all the rest of the people back home.

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.
