1 Samuel 4:17-18

17He who brought the news answered and said, "Israel has fled before the Philistines, and there has also been a great defeat among the people. Your two sons also, Hophni and Phinehas, are dead, and the ark of God has been captured."

18As soon as he mentioned the ark of God, Eli fell over backward from his seat by the side of the gate, and his neck was broken and he died, for the man was old and heavy. He had judged Israel forty years.
