After three years of peace with Syria, Jehoshaphat, king of Judah, visits Ahab. Ahab proposes to recover Ramoth-gilead, and Jehoshaphat agrees, but asks to inquire of the Lord first. About four hundred prophets say he should go up, because the Lord will give it into the king's hand, and Zedekiah, son of Chenaanah, makes iron horns to announce that with them he will gore the Syrians.
Jehoshaphat asks whether there is not another prophet of the Lord. Ahab says there is one, Micaiah, son of Imlah, but he hates him because he never prophesies anything good about him. Micaiah first answers ironically the same as the others, but Ahab demands the truth in the name of the Lord. Then he says he saw Israel scattered on the hills like sheep without a shepherd, and saw the Lord on his throne and a spirit offering to be a lying spirit in the mouth of Ahab's prophets. Zedekiah slaps him and Ahab orders him put in prison on bread and water.
Ahab and Jehoshaphat go up to Ramoth. Ahab disguises himself and asks Jehoshaphat to wear his royal robes. The king of Syria orders his captains to attack only the king of Israel, but on recognizing Jehoshaphat they turn back. A man shoots his bow at random and strikes Ahab between the joints of his armor. Ahab dies at evening, and the dogs lick his blood when his chariot is washed in Samaria, as the Lord had said.
The chapter summarizes that Jehoshaphat reigned twenty-five years and did right like Asa, though he did not remove the high places, and that his fleet to go to Ophir was wrecked at Ezion-geber. Ahaziah, son of Ahab, reigns in Israel and follows the way of his parents.
