1 Samuel 5:6-7

6Now 1the hand of the Lord was heavy on the Ashdodites, and 2He made them feel devastated and struck them with 3tumors, both Ashdod and its territories.

7When the men of Ashdod saw that it was so, they said, “The ark of the God of Israel must not remain with us, because His hand is severe on us and on Dagon our god.”
