1 Samuel 4:10-11, 18

And did they ever fight! It turned into a rout. They thrashed Israel so mercilessly that the Israelite soldiers ran for their lives, leaving behind an incredible thirty thousand dead. As if that wasn’t bad enough, the Chest of God was taken and the two sons of Eli—Hophni and Phinehas—were killed.

At the words, “Chest of God,” Eli fell backward off his stool where he sat next to the gate. Eli was an old man, and very fat. When he fell, he broke his neck and died. He had led Israel forty years.
