1 Kings 22:18-22
22:18 The king of Israel said to Jehoshaphat, “Didn’t I tell you he does not prophesy prosperity for me, but disaster?”
22:19 Micaiah said, “That being the case, hear the word of the Lord. I saw the Lord sitting on his throne, with all the heavenly assembly standing on his right and on his left.
22:20 The Lord said, ‘Who will deceive Ahab, so he will attack Ramoth Gilead and die there?’ One said this and another that.
22:21 Then a spirit stepped forward and stood before the Lord. He said, ‘I will deceive him.’ The Lord asked him, ‘How?’
22:22 He replied, ‘I will go out and be a lying spirit in the mouths of all his prophets.’ The Lord said, ‘Deceive and overpower him. Go out and do as you have proposed.’
