What did the Philistines include when they returned the Ark of the Covenant?

The Philistines returned the Ark of the Covenant along with five golden rats and five golden tumors as a form of restitution for the troubles they encountered while in possession of the Ark. This act is documented in the biblical narrative found in 1 Samuel 6. After experiencing severe plagues, they attributed their suffering to the presence of the Ark and sought a way to appease the God of Israel. The inclusion of the gold rats symbolized their acknowledgment of the afflictions caused by the mice that plagued their land, while the tumors represented their suffering from disease during the time the Ark was with them. This unique offering served as a means of expressing contrition and a desire to rid themselves of the calamities associated with the Ark.
