1 Kings 13:11-19

Verse 11

An old prophet - Probably once a prophet of the Lord, who had fallen from his steadfastness, and yet not so deeply as to lose the knowledge of the true God, and join with Jeroboam in his idolatries. We find he was not at the king's sacrifice, though his sons were there; and perhaps even they were there, not as idolaters, but as spectators of what was done.
Verse 14

And went after the man of God - I can hardly think that this was with any evil design. His sons had given him such an account of the prediction, the power, and influence of this prophet, that he wished to have a particular acquaintance with him, in order that he might get farther information relative to the solemn import of the prophecy which he had denounced against the idolatry at Beth-el. This good man could not have been an object of the old prophet's malevolence.
Verse 18

An angel spake unto me - That he lied unto him is here expressly asserted, and is amply proved by the event. But why should he deceive him? The simple principle of curiosity to know all about this prediction, and the strange facts which had taken place, of which he had heard at second hand by means of his sons, was sufficient to induce such a person to get the intelligence he wished by any means. We may add to this, that, as he found the man of God sitting under an oak, probably faint with fatigue and fasting, for he had had no refreshment, his humanity might have led him to practice this deception, in order to persuade him to take some refreshment. Having fallen from God, as I have supposed, 1Kgs 13:11, his own tenderness of conscience was gone; and he would not scruple to do a moral evil, if even a temporal good could come of it. Again, is it not possible that the old prophet was himself deceived? for, though he lied unto him, it is possible that he was not conscious of his lie, for Satan, as an angel of light, might have deceived him in order to lead him to deceive the other. He does not say, as the man of God did, It was said to me by the word of the Lord; no: but, An angel spake unto me by the word of the Lord. And I think it very likely that an angel did appear to him on the occasion; an angel of darkness and idolatry, in the garb of an angel of light, who wished to use him as an instrument to bring discredit on the awful transactions which had lately taken place, and to destroy him who had foretold the destruction of his power and influence.
Verse 19

So he went back with him - He permitted himself to be imposed on; he might have thought, as he had accomplished every purpose for which God sent him, and had actually begun to return by another way, God, who had given him the charge, had authority to say, "As thy purpose was to obey every injunction, even to the letter, I now permit thee to go with this old prophet, and take some refreshment." Now God might as well have dispensed with this part of the injunction, as he did in the case of Abraham: Take thy son Isaac, thy only son, whom thou lovest - and offer him for a burnt-offering; but, when he saw his perfect readiness, he dispensed with the actual offering, and accepted a ram in his stead. Thus much may be said in vindication of the man of God: but if this be so, why should he be punished with death, for doing what he had reason and precedent to believe might be the will of God? I answer: He should not have taken a step back, till he had remission of the clause from the same authority which gave him the general message. He should have had it from the word of the Lord to himself, in both cases, as Abraham had; and not taken an apparent contradiction of what was before delivered unto him, from the mouth of a stranger, who only professed to have it from an angel, who pretended to speak unto him by the word of the Lord. In this, and in this alone, lay the sinfulness of the act of the man of God, who came out of Judah.
