'Princes' in the Bible

He raiseth up the poor out of the dust, He lifteth up the needy from the dunghill, To make them sit with princes, And inherit the throne of glory: For the pillars of the earth are Jehovah's, And he hath set the world upon them.

Then the princes 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 much set by.

Then said the princes of the Philistines, What do these Hebrews here ? And Achish said unto the princes of the Philistines, Is not this David, the servant of Saul the king of Israel, who hath been with me these days, or rather these years, and I have found no fault in him since he fell away unto me unto this day?

But he princes of the Philistines were wroth with him; and the princes of the Philistines said unto him, Make the man return, that he may go back to his place where thou hast appointed him, and let him not go down with us to battle, lest in the battle he become an adversary to us: for wherewith should this fellow reconcile himself unto his lord? should it not be with the heads of these men?

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