1 Samuel 5:7-9

7When the people of Ashdod saw what was happening, they said, “The ark of the god of Israel must not stay here with us, because his hand is heavy on us and on Dagon our god.”

8So they called together all the rulers of the Philistines and asked them, “What shall we do with the ark of the god of Israel?” They answered, “Have the ark of the god of Israel moved to Gath.” So they moved the ark of the God of Israel. 9But after they had moved it, the LORD ’s hand was against that city, throwing it into a great panic. He afflicted the people of the city, both young and old, with an outbreak of tumors. Or with tumors in the groin (see Septuagint)
