1 Samuel 13:3

And Jonathan smote the garrison of the Philistines that was in Geba, on the hill near his home town, 1 Samuel 10:5, thereby taking the offensive against the invaders; and the Philistines heard of it. And Saul blew the trumpet throughout all the land, saying, Let the Hebrews hear; the Israelites, especially those living west of Jordan, should know of Jonathan's heroic exploit, arouse themselves to action against the oppressors, and fight for their freedom.
