The prophet Micaiah related the Word of the Lord to kings Ahab and Jehoshaphat. Did he (Micaiah) really see the Lord and the host of heaven, or was this a vision?:
1 Kings 22:20-21: Micaiah said, “Therefore, hear the word of the LORD. I saw the LORD sitting on His throne, and all the host of heaven standing by Him on His right and on His left. The LORD said, ‘Who will entice Ahab to go up and fall at Ramoth-gilead?’ And one said this while another said that. Then a spirit came forward and stood before the LORD and said, ‘I will entice him.’"
If the "spirit that came forward" was about to deceive Ahab, could it really have been an angel?
