1 Samuel 6:17-18

17These are the golden tumors which the Philistines returned as a guilt offering to the Lord: one for Ashdod, one for Gaza, one for Ashkelon, one for Gath and one for Ekron [the five chief cities of the Philistines];

18also the golden mice, according to the number of all the cities of the Philistines belonging to the five lords, both fortified cities and [unwalled] country villages. The large stone on which the Levites set the ark of the Lord remains a witness to this day in the field of Joshua of Beth-shemesh.
