1 Samuel 6:17-18

These are the gold tumors the Philistines sent as a guilt offering to the LORD—one each for Ashdod, Gaza, Ashkelon, Gath and Ekron. And the number of the gold rats was according to the number of Philistine towns belonging to the five rulers—the fortified towns with their country villages. The large rock on which the Levites set the ark of the LORD is a witness to this day in the field of Joshua of Beth Shemesh.
