Translation
Therefore, look! YHVH (read Adonai) has put a lying spirit in the mouth of all these prophets of yours, and YHVH (read Adonai) has declared disaster against you.”
Paraphrase
Pay attention to this, Ahab, because here’s the bottom line, THE ETERNAL AND PERSONAL GOD tested you many times with deceiving spirits. In your case they came in the form of the prophets you have gathered around you. How did you fare in those tests? You failed every test. God is patient, but you have come to the point of exhausting His patience; it is time for punishment. Based on your track record, God has determined that you deserve death, and you deserve it right away.”
