1 Kings 13:24

Slew him — But why doth God punish a good man so severely for so small an offence? His sin was not small, for it was a gross disobedience to a positive command. And it cannot seem strange if God should bring his deserved death upon him in this manner, for the accomplishment of his own glorious designs, to vindicate his own justice from the imputation of partiality; to assure the truth of his predictions, and thereby provoke Jeroboam and his idolatrous followers to repentance; and to justify himself in all his dreadful judgments which he intended to inflict upon Jeroboam's house, and the whole kingdom of Israel.
