1 Chronicles 10:10

And they put his armour in the house of their gods, and fastened his head in the temple of Dagon.

Cross-reference

1 Samuel 31:10 gives the parallel account: armor in Ashtaroth's temple and body fastened to wall — differing details from head in Dagon's temple.

1 Samuel 5:2-7 describes Dagon falling before the ark — a later contrast: Dagon's temple receives Saul's head but cannot stand before God.
