Charles Ellicott Commentary 1 Kings 22:24

"Then Zedekiah the son of Chenaanah came near, and smote Micaiah on the cheek, and said, Which way went the Spirit of Jehovah from me to speak unto thee?" — 1 Kings 22:24 (ASV)

Smote Micaiah on the cheek. — The act is not only an expression of contempt (Micah 5:1; Matthew 5:39) but also of professed indignation at words of blasphemy against God or contempt for His representatives; this is clearly seen when it is recorded as directed against our Lord (John 18:22–23) or against St. Paul (Acts 23:2).

The words that accompany it evidently convey a sarcastic reference to the knowledge of God's secret dealings, implied in Micaiah’s vision, aiming to turn it into ridicule.

Micaiah’s answer accordingly passes them by, and merely declares the shame and terror with which Zedekiah will later discover the truth of the prophecy of evil. Josephus offers a curious addition: that Zedekiah challenged Micaiah to cause his hand to wither, like the hand of Jeroboam at Bethel, and dismissed his prophecy as inconsistent with that of Elijah (Antt. viii. 15, § 4).
