1 Samuel 4:17-18

17The messenger replied, “Israel has fled before the Philistines and there has also been a great slaughter among the people. Also your two sons, Hophni and Phinehas, are dead, and the ark of God has been taken.”

18When he mentioned the ark of God, Eli fell off the seat backwards by the side of the [city] gate. His neck was broken and he died, for he was old and heavy. He had judged Israel for forty years.
