1 Kings 20:35

And a certain man of the sons of the prophets
Which the Jews take to be Micaiah, and so Josephus ^F21, which is probable; the same that had been with Ahab more than once; and, whoever he was, it is not unlikely that he was the same, since Ahab knew him when his disguise was off, ( 1 Kings 20:41 ) ,

said unto his neighbour, in the word of the Lord, smite me, I pray
thee;
told his neighbour, that by the command of God he was ordered to bid him smite him, so as to wound him:

and the man refused to smite him;
being his neighbour, and perhaps a fellow prophet, and having an affection for him.
