I Samuel 5:4

But they were obliged to give up this notion when they found the god lying on his face upon the ground again the next morning in front of the ark of Jehovah, and in fact broken to pieces, so that Dagon's head and the two hollow hands of his arms lay severed upon the threshold, and nothing was left but the trunk of the fish (דּגון). The word Dagon, in this last clause, is used in an appellative sense, viz., the fishy part, or fish's shape, from דּג, a fish. המּפתּן is no doubt the threshold of the door of the recess in which the image was set up. We cannot infer from this, however, as Thenius has done, that with the small dimensions of the recesses in the ancient temples, if the image fell forward, the pieces named might easily fall upon the threshold. This naturalistic interpretation of the miracle is not only proved to be untenable by the word כּרתות, since כּרוּת means cut off, and not broken off, but is also precluded by the improbability, not to say impossibility, of the thing itself. For if the image of Dagon, which was standing by the side of the ark, was thrown down towards the ark, so as to lie upon its face in front of it, the pieces that were broken off, viz., the head and hands, could not have fallen sideways, so as to lie upon the threshold. Even the first fall of the image of Dagon was a miracle. From the fact that their god Dagon lay upon its face before the ark of Jehovah, i.e., lay prostrate upon the earth, as though worshipping before the God of Israel, the Philistines were to learn, that even their supreme deity had been obliged to fall down before the majesty of Jehovah, the God of the Israelites. But as they did not discern the meaning of this miraculous sign, the second miracle was to show them the annihilation of their idol through the God of Israe…

It is now time to enquire what has become of the ark of God; we cannot but think that we shall hear more of that sacred treasure. I should have thought the next news would have been that all Israel, from Dan to Beersheba, had gathered together as one man, with a resolution to bring it back, or die in the attempt; but we find not any motion made of that kind, so little was there of zeal or courage left among them. Nay, we do not find that they desired a treaty with the Philistines about the ransom of it, or offered any thing in lieu of it. "It is gone, and let it go." Many have softness enough to lament the loss of the ark that have not hardiness enough to take one step towards the recovery of it, any more than Israel here. If the ark will help itself it may, for they will not help it. Unworthy they were of the name of Israelites that could thus tamely part with the glory of Israel. God would therefore take the work into his own hands and plead his own cause, since men would not appear for him. We are told in this chapter, I. How the Philistines triumphed over the ark (Sa1 5:1, Sa1 5:2), and, II. How the ark triumphed over the Philistines, 1. Over Dagon their god (Sa1 5:3-5). 2. Over the Philistines themselves, who were sorely plagued with emerods, and made weary of the ark; the men of Ashdod first (Sa1 5:6, Sa1 5:7), then the men of Gath (Sa1 5:8, Sa1 5:9), and lastly those of Ekron, which forced them at length upon a resolution to send the ark back to the land of Israel; for when God judgeth he will overcome.
