1 Kings 22:24 - Ellicott's Commentary On The Whole Bible

Smote Micaiah on the cheek. — The act is not only the expression of contempt (see Isaiah 1:6; Micah 5:1; Matthew 5:39), but of professed indignation at words of blasphemy against God, or of contempt for His vicegerents; as is seen clearly, when it is recorded as directed against Our Lord or against St. Paul (John 18:22-23; Acts 23:2). The words which accompany it evidently convey a sarcastic reference to the knowledge of the secret dealings of God, implied in Micaiah’s vision, with a view to turn it into ridicule. Micaiah’s answer accordingly passes them by, and merely declares the shame and terror, with which Zedekiah shall find out hereafter the truth of the prophecy of evil. Josephus has a curious addition, that Zedekiah challenged Micaiah to wither up his hand, like the hand of Jeroboam at Bethel, and scouted his prophecy as inconsistent with that of Elijah (Antt. viii. 15, § 4).
