1 Samuel 14:20-22

14:20 Saul and all the army that was with him assembled and marched into battle, where they found the Philistines in total panic killing one another with their swords. 14:21 The Hebrews who had earlier gone over to the Philistine side joined the Israelites who were with Saul and Jonathan. 14:22 When all the Israelites who had hidden themselves in the hill country of Ephraim heard that the Philistines had fled, they too pursued them in battle.
