1 Kings 22:3-4, 6

And the king of Israel said to his servants, “Do you know that Ramoth-gilead belongs to us, and we keep quiet and do not take it out of the hand of the king of Syria?” And he said to Jehoshaphat, “Will you go with me to battle at Ramoth-gilead?” And Jehoshaphat said to the king of Israel, “I am as you are, my people as your people, my horses as your horses.”

Then the king of Israel gathered the prophets together, about four hundred men, and said to them, “Shall I go to battle against Ramoth-gilead, or shall I refrain?” And they said, “Go up, for the Lord will give it into the hand of the king.”
