1 Samuel 13:1-4 - Saul Rules Over Israel
1 Saul was [thirty] years old when he began to reign; he ruled over Israel for [forty] years. 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.
3 Jonathan attacked the Philistine outpost that was at Geba and the Philistines heard about it. Then Saul alerted all the land saying, "Let the Hebrews pay attention!" 4 All Israel heard this message, "Saul has attacked the Philistine outpost, and now Israel is repulsive to the Philistines!" So the people were summoned to join Saul at Gilgal.
