1 Kings 22:21, What spirit came before the LORD?

Question: In 1 Kings 22:21 what spirit came before the LORD? Answer: In verse 19 it says that all the hosts of heaven were standing by, on the Lord's right and on His left.  Since the right hand was a place of favor, this might indicate that God spoke to the combined hosts of heaven, both faithful and fallen angels.  So, I believe this was one of the fallen angels (spirits) that volunteered for this task.  Since Ahab wanted to be deceived, God would give him what he wanted.  -PG
