1 Samuel 5:4-6

Amplified Bible

⁴ But when they got up early the next morning, behold, Dagon had [again] fallen on his face on the ground before the ark of the Lord, and his head and both palms of his hands were [lying] cut off on the threshold; only the trunk [portion] of [the idol of] Dagon was left on him. ⁵ This is the reason neither the priests of Dagon nor any who enter Dagon’s house step on the threshold of Dagon in Ashdod to this day.

⁶ Then the hand of the Lord was heavy on the people of Ashdod, and He caused them to be dumbfounded and struck them with ^[a]tumors, both Ashdod and its territory.
