I Samuel 4:4, 11, 17-18

So the people sent to Shiloh, that they might bring from there the ark of the covenant of the LORD of hosts, who dwells between the cherubim. And the two sons of Eli, Hophni and Phinehas, were there with the ark of the covenant of God.

Also the ark of God was captured; and the two sons of Eli, Hophni and Phinehas, died.

So the messenger answered and said, “Israel has fled before the Philistines, and there has been a great slaughter among the people. Also your two sons, Hophni and Phinehas, are dead; and the ark of God has been captured.” Then it happened, when he made mention of the ark of God, that Eli fell off the seat backward by the side of the gate; and his neck was broken and he died, for the man was old and heavy. And he had judged Israel forty years.
