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.

So he went back with him,.... In which he sinned; for as he had most certainly the command of God not to eat and drink in that place, he ought to have had the countermand from the Lord, and not trusted to another person. There are some things indeed which may be said in his favour, and be an apology for him, as that this man was an ancient prophet of the Lord, as he appeared to him; and that though he was forbid to eat and drink with idolaters, yet he thought he might with a prophet of the Lord, and especially as he affirmed he had the direction of an angel of the Lord for it; nor could he conceive that the prophet had any interest to serve by it, but rather it might be chargeable and burdensome to him; and he might think the Lord, out of compassion on him, had countermanded his former orders, and the circumstances he was in might the more incline him to listen to these plausible pretences; but, after all, he ought to have taken no directions but from the Lord himself; in this he failed:
and did eat bread in his house, and drink water; contrary to the express command of God.
