1 Kings 22:12

22:12 All the prophets were prophesying the same, saying, “Attack Ramoth Gilead! You will succeed; the Lord will hand it over to the king.”

1 Kings 22:20-23

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.’ 22:23 So now, look, the Lord has placed a lying spirit in the mouths of all these prophets of yours; but the Lord has decreed disaster for you.”
