1 Samuel 13:2-4

2Saul chose three thousand men from Israel; two thousand were with him at Mikmash and in the hill country of Bethel, and a thousand were with Jonathan at Gibeah in Benjamin. The rest of the men he sent back to their homes.

3Jonathan attacked the Philistine outpost at Geba, and the Philistines heard about it. Then Saul had the trumpet blown throughout the land and said, “Let the Hebrews hear!”

4So all Israel heard the news: “Saul has attacked the Philistine outpost, and now Israel has become obnoxious to the Philistines.” And the people were summoned to join Saul at Gilgal.
