1 Kings 22:19-22

¹⁹And he added and said: Hear thou therefore the word of the Lord: I saw the Lord sitting on his throne, and all the army of heaven standing by him on the right hand and on the left:

²⁰And the Lord said: Who shall deceive Achab king of Israel, that he may go up, and fall at Ramoth Galaad? And one spoke words of this manner, and another otherwise.

²¹And there came forth a spirit, and stood before the Lord, and said: I will deceive him. And the Lord said to him: By what means?

²²And he said: I will go forth, and be a lying spirit in the mouth of all his prophets. And the Lord said: Thou shalt deceive him, and shalt prevail: a go forth, and do so.
