2 Chronicles 18:1-8

Now Jehoshaphat had great riches and honor, and he made a marriage alliance with Ahab. After some years he went down to Ahab in Samaria. And Ahab killed an abundance of sheep and oxen for him and for the people who were with him, and induced him to go up against Ramoth-gilead. Ahab king of Israel said to Jehoshaphat king of Judah, “Will you go with me to Ramoth-gilead?” He answered him, “I am as you are, my people as your people. We will be with you in the war.” And Jehoshaphat said to the king of Israel, “Inquire first for the word of the LORD.” Then the king of Israel gathered the prophets together, four hundred men, and said to them, “Shall we go to battle against Ramoth-gilead, or shall I refrain?” And they said, “Go up, for God will give it into the hand of the king.” But Jehoshaphat said, “Is there not here another prophet of the LORD of whom we may inquire?” And the king of Israel said to Jehoshaphat, “There is yet one man by whom we may inquire of the LORD, Micaiah the son of Imlah; but I hate him, for he never prophesies good concerning me, but always evil.” And Jehoshaphat said, “Let not the king say so.” Then the king of Israel summoned an officer and said, “Bring quickly Micaiah the son of Imlah.”
