1 Samuel 14:13-15, 20-23

Jonathan shouted to his armor bearer, “Up! Follow me! GOD has turned them over to Israel!” Jonathan scrambled up on all fours, his armor bearer right on his heels. When the Philistines came running up to them, he knocked them flat, his armor bearer right behind finishing them off, bashing their heads in with stones. In this first bloody encounter, Jonathan and his armor bearer killed about twenty men. That set off a terrific upheaval in both camp and field, the soldiers in the garrison and the raiding squad badly shaken up, the ground itself shuddering—panic like you’ve never seen before!

Saul immediately called his army together and they went straight to the battle. When they got there they found total confusion—Philistines swinging their swords wildly, killing each other. Hebrews who had earlier defected to the Philistine camp came back. They now wanted to be with Israel under Saul and Jonathan. Not only that, but when all the Israelites who had been hiding out in the backwoods of Ephraim heard that the Philistines were running for their lives, they came out and joined the chase. GOD saved Israel! What a day! The fighting moved on to Beth Aven. The whole army was behind Saul now—ten thousand strong!—with the fighting scattering into all the towns throughout the hills of Ephraim.
