2 brought it into the shrine of Dagon, and placed it alongside the idol of Dagon. 3 Next morning when the citizens of Ashdod got up, they were shocked to find Dagon toppled from his place, flat on his face before the Chest of God. They picked him up and put him back where he belonged. 4 First thing the next morning they found him again, toppled and flat on his face before the Chest of God. Dagon's head and arms were broken off, strewn across the entrance. Only his torso was in one piece.

Commentary on 1 Samuel 5:1-5
(Read 1 Samuel 5:1-5)
See the ark's triumph over Dagon. Thus the kingdom of Satan will certainly fall before the kingdom of Christ, error before truth, profaneness before godliness, and corruption before grace in the hearts of the faithful. When the interests of religion seem to be ready to sink, even then we may be confident that the day of their triumph will come. When Christ, the true Ark of the covenant, really enters the heart of fallen man, which is indeed Satan's temple, all idols will fall, every endeavour to set them up again will be vain, sin will be forsaken, and unrighteous gain restored; the Lord will claim and possess the throne. But pride, self-love, and worldly lusts, though dethroned and crucified, still remain within us, like the stump of Dagon. Let us watch and pray that they may not prevail. Let us seek to have them more entirely destroyed.
