1 Samuel 4:16-18

16And the man said to Eli, I am he that came out of the battle, and I have fled to-day out of the battle. And he said, What has taken place, my son?

17And the messenger answered and said, Israel has fled before the Philistines, and there has been also a great slaughter among the people, and thy two sons also, Hophni and Phinehas, are dead, and the ark of 1God is taken.

18And it came to pass, when he mentioned the ark of 2God, that he fell from off the seat backward by the side of the gate, and his neck broke, and he died; for the man was old, and heavy. And he had judged Israel forty years.
