Charles Ellicott Commentary 1 Kings 19:15

"And Jehovah said unto him, Go, return on thy way to the wilderness of Damascus: and when thou comest, thou shalt anoint Hazael to be king over Syria;" — 1 Kings 19:15 (ASV)

Go, return. —The charge indirectly conveys a double rebuke.

His cry of disappointment, Lord ... I am not better than my fathers, implying that he stood out beyond all others to meet the stern requirements of the time, is met by the charge to delegate to others the task of God’s vengeance. His complaint, I, even I alone, am left, is similarly met by the revelation of the faithful remnant—the seven thousand who had not bowed to Baal—unknown to him, perhaps to one another, but known and loved by God.
