1 Samuel 6:4-5

Then they said, “What shall the guilt offering be which we shall return to Him?” They answered, “Five golden tumors and five golden mice, according to the number of the lords (governors) of the Philistines, for one plague was on all of you and on your lords. So you shall make replicas of your tumors and of your mice that ravage the land, and give glory to the God of Israel; perhaps He will lighten His hand [of judgment] on you and your gods and your land.
