1 Samuel 13:3-4

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!” 13:4 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.
