'Commanders' in the Bible

He will appoint for himself commanders of thousands and of fifties, and some to do his plowing and to reap his harvest and to make his weapons of war and equipment for his chariots.

Then the commanders of the Philistines went out to battle, and it happened as often as they went out, that David behaved himself more wisely than all the servants of Saul. So his name was highly esteemed.

Saul said to his servants who stood around him, “Hear now, O Benjamites! Will the son of Jesse also give to all of you fields and vineyards? Will he make you all commanders of thousands and commanders of hundreds?

Then the commanders of the Philistines said, “What are these Hebrews doing here?” And Achish said to the commanders of the Philistines, “Is this not David, the servant of Saul the king of Israel, who has been with me these days, or rather these years, and I have found no fault in him from the day he deserted to me to this day?”

But the commanders of the Philistines were angry with him, and the commanders of the Philistines said to him, “Make the man go back, that he may return to his place where you have assigned him, and do not let him go down to battle with us, or in the battle he may become an adversary to us. For with what could this man make himself acceptable to his lord? Would it not be with the heads of these men?

But Achish replied to David, “I know that you are pleasing in my sight, like an angel of God; nevertheless the commanders of the Philistines have said, ‘He must not go up with us to the battle.’
