1 Samuel 4:2, 3, 10, 11

The Philistines deployed their forces to meet Israel, and as the battle spread, Israel was defeated by the Philistines, who killed about four thousand of them on the battlefield.

When the soldiers returned to camp, the elders of Israel asked, “Why did the LORD bring defeat on us today before the Philistines? Let us bring the ark of the LORD’s covenant from Shiloh, so that he may go with us and save us from the hand of our enemies.”

So the Philistines fought, and the Israelites were defeated and every man fled to his tent. The slaughter was very great; Israel lost thirty thousand foot soldiers.

The ark of God was captured, and Eli’s two sons, Hophni and Phinehas, died.
