'Philistine Rulers' in the Bible

And the rulers of the Philistines were angry with him. And the Philistine rulers said to him, Send the man back, and he shall return to his place where you have appointed him. And he shall not go down with us to battle, and shall not become an enemy to us in battle. For with what should he reconcile himself to his master? Should it not be with the heads of these men?
