1 Samuel 4:17-18

He who brought the news answered, “Israel has fled before the Philistines, and there has been also a great slaughter among the people. Your two sons also, Hophni and Phinehas, are dead, and the ark of God has been captured.”

When he made mention of the ark of God, Eli fell from off his seat backward by the side of the gate; and his neck broke, and he died; for he was an old man, and heavy. He had judged Israel forty years.
