2KI 3:7

7 And he sent to Jehoshaphat, king of Judah, and said, The king of Moab hath gone away from me; come thou with me against him to battle. And Jehoshaphat answered, I shall go up with thee; he that is mine, is thine (or all that is mine, is thine); my people is thy people; and mine horses be thine horses.
