2 Chronicles 18:4

1 Now Jehoshaphat had riches and honor in abundance, and he allied himself with Ahab by marriage.

2 And some years later he went down to visit Ahab in Samaria, where Ahab sacrificed many sheep and cattle for him and the people with him, and urged him to march up to Ramoth-gilead.

3 Ahab king of Israel asked Jehoshaphat king of Judah, “Will you go with me against Ramoth-gilead?” And Jehoshaphat replied, “I am like you, and my people are your people; we will join you in the war.”

4 But Jehoshaphat also said to the king of Israel, “Please inquire first for the word of the LORD.”

5 So the king of Israel assembled the prophets, four hundred men, and asked them, “Should we go to war against Ramoth-gilead, or should we refrain?” “Go up,” they replied, “and God will deliver it into the hand of the king.”

6 But Jehoshaphat asked, “Is there not still a prophet of the LORD here of whom we can inquire?”

7 The king of Israel answered, “There is still one man who can ask the LORD, but I hate him because he never prophesies anything good for me, but only bad. He is Micaiah son of Imlah.” “The king should not say that!” Jehoshaphat replied.
