'Outpost' in the Bible

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!"

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.
