1 Samuel 13:2-3

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.

13:3 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!”
