Dagon

Now the Philistines took the ark of God and brought it from Ebenezer to Ashdod. Then the Philistines took the ark of God and brought it to the house of Dagon and set it by Dagon. When the Ashdodites arose early the next morning, behold, Dagon had fallen on his face to the ground before the ark of the LORD. So they took Dagon and set him in his place again. But when they arose early the next morning, behold, Dagon had fallen on his face to the ground before the ark of the LORD. And the head of Dagon and both the palms of his hands were cut off on the threshold; only the trunk of Dagon was left to him.

In Exodus 20, God says 'You shall have no other gods before Me.' In this passage (1 Samuel 5:1-4) the god of the Philistines couldn't even remain in his place before the ark! This is the same god to whom the Philistines offered a great sacrifice for giving Samson, their enemy, into their hands (Judges 16:23). Alas, only a few moments later Samson was to, quite literally, bring the house down on the Philistines, God listening to Samson's call.

I am reminded of Psalm 95:

O come, let us sing for joy to the LORD, let us shout joyfully to the rock of our salvation... for the LORD is a great God and a great King above all gods...
