Adam Clarke on 1 Kings 22:19

I saw the Lord sitting on his throne - This is a mere parable, and only tells in figurative language, what was in the womb of providence, the events which were shortly to take place, the agents employed in them, and the permission on the part of God for these agents to act. Micaiah did not choose to say before this angry and impious king, "Thy prophets are all liars; and the devil, the father of lies, dwells in them;" but he represents the whole by this parable, and says the same truths in language as forcible, but less offensive.
