1 Kings 13:11

There dwelt an old prophet in Beth-el One to whom and by whom God did sometimes reveal his will, as is manifest from 1 Kings 13:20; and one who had a respect to God's holy prophets, and gave credit to their predictions. But that he was not a truly and uniformly good and pious man is certain, because we here find him guilty of a downright lie, 1 Kings 13:18. And, although a holy prophet, who had lived there before, might possibly have continued in the kingdom of Israel after its separation from Judah, and defection from the true worship of God; yet such a one would not have chosen to reside at Beth-el, the chief seat of idolatry, unless with a design to preach against it: this, it is evident, he did not; for his sons, it appears, were present when Jeroboam stood at the altar, and therefore joined in that idolatrous worship, and yet their father was too timorous to reprove them. He was probably somewhat like the famous Balaam, who was commissioned to utter divers true prophecies, but nevertheless loved the wages of unrighteousness, and was a wicked man.
