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.”

4However, Jehoshaphat said to the king of Israel, “Please request the word of the Lord 1first.” 5So the king of Israel assembled the 2prophets, four hundred men, and said to them, “Should we go to battle against Ramoth-gilead, or should I refrain?” And they said, “Go up, for God will hand it over to the king.”
