Which way went the Spirit of the Lord from me - This is an expression of as great insolence as the act was of brutal aggression. "Did the Spirit of the Lord, who rests solely upon me, condescend to inspire thee? Was it at this ear [where he smote him] that it entered, in order to hold communion with thee?" Josephus tells an idle rabbinical tale about this business, which is as unworthy of repetition as it is of credit. See his Antiq. of the Jews, book viii., c. 10.
Smote Micaiah on the cheek - As Micaiah had been brought from prison 1 Kings 22:26, it is probable that his hands were bound.
The prophet, thus standing before the great ones of the earth, bound and helpless, bearing testimony to the truth, and for his testimony smitten on the face by an underling, whose blow he receives without either shame or anger, is a notable type of our Lord before Caiaphas suffering the same indignity.
Which way - Zedekiah‘s meaning may perhaps be expounded as follows:
“The Spirit of Yahweh certainly came to me, and inspired me with the answer which I gave. If He afterward went to thee, as thou sayest that He did, perhaps thou canst tell us - as all the secrets of the invisible world are, thou pretendest, open to thee - which way He took.”
