Ishodad of Merv : Some authors assert that [the old prophet] was not an impostor but invited [the true prophet] to eat out of human sympathy in order to refresh and thank him for admonishing Jeroboam. And that is why God did not harm him as a consequence of this. According to others, he was a false prophet because, if he had been a true prophet, as others maintained, he would have not seduced a true prophet, and his children would not have served in a house of idols; therefore it was in order to seduce him that he went to meet the prophet. — BOOKS OF SESSIONS 1 Kings 13:11
