1 Samuel 4:6-9
6-9Then they learned that the Chest of God had entered the Hebrew camp. The Philistines panicked: "Their gods have come to their camp! Nothing like this has ever happened before. We're done for! Who can save us from the clutches of these supergods? These are the same gods who hit the Egyptians with all kinds of plagues out in the wilderness. On your feet, Philistines! Courage! We're about to become slaves to the Hebrews, just as they have been slaves to us. Show what you're made of! Fight for your lives!"
10-11And did they ever fight! It turned into a rout. They thrashed Israel so mercilessly that the Israelite soldiers ran for their lives, leaving behind an incredible thirty thousand dead. As if that wasn't bad enough, the Chest of God was taken and the two sons of Eli—Hophni and Phinehas—were killed.
