1 Kings 20:24 - Joseph Benson’s Commentary on the Old and New Testaments

Do this take the kings away, &c. He had made the thirty- two kings, who were his tributaries, chief commanders in his former army; which his counsellors represent to him as a great error, and therefore advise him to displace them, and put his own captains in their stead, who would fight better. The kings, they thought, had had a softer education; and, being less inured to hardships, and less experienced in military matters, were less fit for service: besides, being many of them mercenaries, and therefore less concerned in his good success, they judged they would be more cautious in venturing themselves, and risking their lives in his cause, and not so obedient to discipline, as captains from his own subjects would be. These latter, they supposed, would faithfully obey the commands of their general, to whom the kings would not readily yield, and would use their utmost skill and valour for their own interest and advancement.
