1 Kings 22:5

And he said unto Jehoshaphat, Wilt thou go with me to battle to Ramothgilead? And Jehoshaphat said to the king of Israel, I am as thou art, my people as thy people, my horses as thy horses.

Then the king of Israel gathered the prophets together, about four hundred men, and said unto them, Shall I go against Ramothgilead to battle, or shall I forbear? And they said, Go up; for the Lord shall deliver it into the hand of the king.
