20 It happened, as they sat at the table, that the word of Yahweh came to the prophet who brought him back; 21 and he cried to the man of God who came from Judah, saying, “Thus says Yahweh, ‘Because you have been disobedient to the mouth of Yahweh, and have not kept the commandment which Yahweh your God commanded you, 22 but came back, and have eaten bread and drunk water in the place of which he said to you, “Eat no bread, and drink no water;” your body shall not come to the tomb of your fathers.’”

23 It happened, after he had eaten bread, and after he had drunk, that he saddled the donkey for the prophet whom he had brought back. 24 When he had gone, a lion met him by the way, and killed him. His body was cast in the way, and the donkey stood by it. The lion also stood by the body. 25 Behold, men passed by, and saw the body cast in the way, and the lion standing by the body; and they came and told it in the city where the old prophet lived.

Commentary on 1 Kings 13:11-22

(Read 1 Kings 13:11-22)

The old prophet's conduct proves that he was not really a godly man. When the change took place under Jeroboam, he preferred his ease and interest to his religion. He took a very bad method to bring the good prophet back. It was all a lie. Believers are most in danger of being drawn from their duty by plausible pretences of holiness. We may wonder that the wicked prophet went unpunished, while the holy man of God was suddenly and severely punished. What shall we make of this? The judgments of God are beyond our power to fathom; and there is a judgment to come. Nothing can excuse any act of wilful disobedience. This shows what they must expect who hearken to the great deceiver. They that yield to him as a tempter, will be terrified by him as a tormentor. Those whom he now fawns upon, he will afterwards fly upon; and whom he draws into sin, he will try to drive to despair.

Commentary on 1 Kings 13:23-34

(Read 1 Kings 13:23-34)

God is displeased at the sins of his own people; and no man shall be protected in disobedience, by his office, his nearness to God, or any services he has done for him. God warns all whom he employs, strictly to observe their orders. We cannot judge of men by their sufferings, nor of sins by present punishments; with some, the flesh is destroyed, that the spirit may be saved; with others, the flesh is pampered, that the soul may ripen for hell. Jeroboam returned not from his evil way. He promised himself that the calves would secure the crown to his family, but they lost it, and sunk his family. Those betray themselves who think to support themselves by any sin whatever. Let us dread prospering in sinful ways; pray to be kept from every delusion and temptation, and to be enabled to walk with self-denying perseverance in the way of God's commands.
