1 Maccabees 11:4

And when he came near to Azotus, they shewed him the temple of Dagon that was burnt, and Azotus and the suburbs thereof that were destroyed, and the bodies that were cast abroad and them that he had burnt in the battle; for they had made heaps of them by the way where he should pass.
