1 Samuel 5:3-7

3And when the people of Ashdod rose early the next day, behold, Dagon had fallen face downward on the ground before the ark of the LORD. So they took Dagon and put him back in his place. 4But when they rose early on the next morning, behold, Dagon had fallen face downward on the ground before the ark of the LORD, and the head of Dagon and both his hands were lying cut off on the threshold. Only the trunk of Dagon was left to him. 5This is why the priests of Dagon and all who enter the house of Dagon do not tread on the threshold of Dagon in Ashdod to this day. 6The hand of the LORD was heavy against the people of Ashdod, and he terrified and afflicted them with tumors, both Ashdod and its territory. 7And when the men of Ashdod saw how things were, they said, “The ark of the God of Israel must not remain with us, for his hand is hard against us and against Dagon our god.”
