John Gill Commentary 1 Kings 22:26

"And the king of Israel said, Take Micaiah, and carry him back unto Amon the governor of the city, and to Joash the king`s son;" — 1 Kings 22:26 (ASV)

And the king of Israel said
To some of his officers:

take Micaiah, and carry him back unto Amon the governor of the city :
the chief magistrate under the king; a sort of sheriff, who had the care of malefactors, and of all committed to prison, from whom he was received by the messenger, and now sent back to him:

and to Joash the king's son ;
who might be over his household, as sometimes the king's son was, (2 Chronicles 26:21) or might be viceroy while the king was without the city, and at the gate of it, and about to go to war.
