2 Chronicles 18:3-5

3Ahab king of Israel said to Jehoshaphat king of Judah, “Will you go with me against Ramoth-gilead?” And he said to him, “I am as you are, and my people as your people, and we will be with you in the battle.”

4Moreover, Jehoshaphat said to the king of Israel, “Please inquire 1first for the word of the Lord.” 5Then the king of Israel assembled the prophets, four hundred men, and said to them, “Shall we go against Ramoth-gilead to battle, or shall I refrain?” And they said, “Go up, for God will give it into the hand of the king.”
