1 Kings 22:26

carry him back unto Amon As Ahab knew so well how to find Micaiah when he was wanted, it may be that he was already under the charge of Amon, in a sort of libera custodia. But the command in the next verse to put him into prison seems conclusive that he had not been a prisoner before.

Joash the king's son We have nothing to guide us in deciding how this man was related to Ahab, or whether he was so at all. His occupation, in conjunction with Amon the governor of the city, as superintendent of the prison-house renders it improbable that he was very closely connected with the reigning family. On the other hand we can hardly think that Joash would have this title if he were of one of the families which had preceded Omri on the throne of Israel. Each new dynasty would probably clear out of the way any who might be likely to lay claim to the throne.
