So he went back with him, and did eat bread in his house, and drank water.

Matthew Henry's Concise Commentary

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.
