Charles Ellicott Commentary 1 Kings 22:15

"And when he was come to the king, the king said unto him, Micaiah, shall we go to Ramoth-gilead to battle, or shall we forbear? And he answered him, Go up and prosper; and Jehovah will deliver it into the hand of the king." — 1 Kings 22:15 (ASV)

Go, and prosper. —Micaiah is a true disciple of Elijah in the defiant irony of the tone in which he takes up and mocks the utterance of the false prophets so bitterly that he at once shows Ahab his scorn of them and him. But his message is couched in metaphor and symbolic vision, unlike the stern directness of the style of Elijah.
