18 When 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 he was an old man, and heavy. He had judged Israel forty years.

Matthew Henry's Commentary on 1 Samuel 4:18

Commentary on 1 Samuel 4:12-18

(Read 1 Samuel 4:12-18)

The defeat of the army was very grievous to Eli as a judge; the tidings of the death of his two sons, to whom he had been so indulgent, and who, as he had reason to fear, died impenitent, touched him as a father; yet there was a greater concern on his spirit. And when the messenger concluded his story with, "The ark of God is taken," he is struck to the heart, and died immediately. A man may die miserably, yet not die eternally; may come to an untimely end, yet the end be peace.
