'Lords of the Philistines' in the Bible

These nations included the five lords of the Philistines, all of the Canaanites, the Sidonians, and the Hivites who lived in Mount Baal-hermon as far as Lebo-hamath.

They sent messengers and gathered together all the lords of the Philistines and asked, "What are we to do with the Ark of the God of Israel?" They said, "Let the Ark of the God of Israel move to Gath." So they moved the Ark of the God of Israel.

"Five gold tumors and five gold mice," they answered, "according to the number of the lords of the Philistines, since the same plague was on all of you and on your lords. Make images of your tumors and images of the mice that are destroying your land, and you are to give glory to the God of Israel. Perhaps he will remove his pressure from you, your gods, and your land.
