1 Samuel 4:5-11

So it happened that as the ark of the covenant of the LORD came into the camp, all [the people of] Israel shouted with a great shout, and the earth resounded. When the Philistines heard the noise of the shout, they said, “What does the noise of this great shout in the camp of the Hebrews mean?” Then they understood that the ark of the LORD had come into the camp. The Philistines were afraid, for they said, “God has come into the camp.” And they said, “Woe [disaster is coming] to us! For nothing like this has happened before. Woe to us! Who will rescue us from the hand of these mighty gods? These are the gods who struck the Egyptians with all kinds of plagues in the wilderness. Take courage, and be men, O Philistines, so that you do not become servants to the Hebrews, as they have been servants to you; act like men and fight!” So the Philistines fought; Israel was defeated and every man fled to his tent. It was a very great defeat, for thirty thousand foot soldiers of Israel fell. Also the ark of God was taken; and the two sons of Eli, Hophni and Phinehas, were killed. [1 Sam 2:34]
