The most famous of the temples of Dagon were at Gaza (Judges 16:23-30) and Ashdod (1 Samuel 5:1-7). In the city of Gaza, Samson pulled down the temple of Dagon and slew “all the lords of the Philistines,” himself also perishing in the ruin (Judges 16:21-30).
In Ashdod, God twice felled the Dagon idol in its temple as the ark of the covenant was displayed before it after capture by the Philistines. God also smote its worshippers with emerods (1 Samuel 5:1-12).
