1 Samuel 6:3-5

3So they said, “If you are going to send the ark of the God of Israel back, do not send it empty. For you must surely return it with a guilt offering. Then you will be healed and it will be revealed to you why His hand has not been removed from you.”

4“What guilt offering should we return to Him?” they asked. So they said, “Five golden tumors and five golden mice—according to the number of the lords of the Philistines, for one plague was on each of you and on your lords.

5So you will make images of your tumors and images of your mice that mar the land, and you must give glory to the God of Israel. Perhaps He will lighten His hand off of you, your gods and your land.
