But he spared Agag, probably to enjoy the glory of displaying so distinguished a captive, and, in like manner, the most valuable portions of the booty, as the cattle. By this wilful and partial obedience to a positive command [1Sa 15:3], complying with it in some parts and violating it in others, as suited his own taste and humor, Saul showed his selfish, arbitrary temper, and his love of despotic power, and his utter unfitness to perform the duties of a delegated king in Israel.

     1Sa 15:10, 11. GOD REJECTS HIS FOR DISOBEDIENCE.
