1 Samuel 6:1-5

1Now the ark of the Lord had been in the country of the Philistines for seven months.

2And the Philistines called for the priests and the diviners (seers), saying, “What shall we do with the ark of the Lord? Let us know how we can send it back to its place.”

3They said, “If you send away the ark of the God of Israel, do not send it empty [without a gift]; but be sure to return [it] to Him [together with] a guilt offering. Then you will be healed, and it will be known to you why His hand is not removed from you.”

4Then 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.

5So 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.
