I Samuel 4:5-10

And when the ark of the covenant of the LORD came into the camp, all Israel shouted so loudly that the earth shook. Now when the Philistines heard the noise of the shout, they said, “What does the sound 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. So the Philistines were afraid, for they said, “God has come into the camp!” And they said, “Woe to us! For such a thing has never happened before. Woe to us! Who will deliver us from the hand of these mighty gods? These are the gods who struck the Egyptians with all the plagues in the wilderness. Be strong and conduct yourselves like men, you Philistines, that you do not become servants of the Hebrews, as they have been to you. Conduct yourselves like men, and fight!” So the Philistines fought, and Israel was defeated, and every man fled to his tent. There was a very great slaughter, and there fell of Israel thirty thousand foot soldiers.
