there came a man of God out of Judah--Who this prophet was cannot be ascertained, He came by divine authority. It could not be either Iddo or Ahijah, for both were alive after the events here related.
Jeroboam stood by the altar to burn incense--It was at one of the annual festivals. The king, to give interest to the new ritual, was himself the officiating priest. The altar and its accompaniments would, of course, exhibit all the splendor of a new and gorgeously decorated temple. But the prophet foretold its utter destruction [Kg1 13:3].
Behold, a child shall be born . . . Josiah by name--This is one of the most remarkable prophecies recorded in the Scriptures; and, in its clearness, circumstantial minuteness, and exact prediction of an event that took place three hundred sixty years later, it stands in striking contrast to the obscure and ambiguous oracles of the heathen. Being publicly uttered, it must have been well known to the people; and every Jew who lived at the accomplishment of the event must have been convinced of the truth of a religion connected with such a prophecy as this. A present sign was given of the remote event predicted, in a visible fissure being miraculously made on the altar. Incensed at the man's license of speech, Jeroboam stretched out his hand and ordered his attendants to seize the bold intruder. That moment the king's arm became stiff and motionless, and the altar split asunder, so that the fire and ashes fell on the floor. Overawed by the effects of his impiety, Jeroboam besought the prophet's prayer. His request was acceded to, and the hand was restored to its healthy state. Jeroboam was artful, and invited the prophet to the royal table, not to do him honor or show his gratitude for the restoration of his hand, but to win, by his courtesy and liberal hospitality, a person whom he could not crush by his power. But the prophet informed him of a divine injunction expressly prohibiting him from all social intercourse with any in the place, as well as from returning the same way. The prohibition not to eat or drink in Beth-el was because all the people had become apostates from the true religion, and the reason he was not allowed to return the same way was lest he should be recognized by any whom he had seen in going.
a lion met him by the way, and slew him--There was a wood near Beth-el infested with lions (Kg2 2:24). This sad catastrophe was a severe but necessary judgment of God, to attest the truth of the message with which the prophet had been charged. All the circumstances of this tragic occurrence (the undevoured carcass, the untouched ass, the passengers unmolested by the lion, though standing there) were calculated to produce an irresistible impression that the hand of God was in it.
