1 Samuel 5:7-8
7-8When the leaders of Ashdod saw what was going on, they decided, "The chest of the god of Israel has got to go. We can't handle this, and neither can our god Dagon." They called together all the Philistine leaders and put it to them: "How can we get rid of the chest of the god of Israel?"
The leaders agreed: "Move it to Gath." So they moved the Chest of the God of Israel to Gath.
9But as soon as they moved it there, God came down hard on that city, too. It was mass hysteria! He hit them with tumors. Tumors broke out on everyone in town, young and old.
