'Rulers Of The Philistines' in the Bible

Then the rulers of the Philistines went forth, and it came to pass, as often as they went forth, that David behaved himself more wisely than all the servants of Saul, so that his name was very precious.

Then the rulers of the Philistines said, What [are] these Hebrews? And Achish said to the rulers of the Philistines, Is not this David, the servant of Saul the king of Israel, who has been with me these days, or [rather] these year

But the rulers of the Philistines were angry with him. And the rulers of the Philistines said to him, Make the man return, that he may go back to his place where thou have appointed him, and let him not go down with us to battle, l

And Achish answered and said to David, I know that thou are good in my sight, as an agent of God, notwithstanding the rulers of the Philistines have said, He shall not go up with us to the battle.
