1 Kings 22:32-33
32-33When the chariot commanders saw Jehoshaphat they said, "There he is! The king of Israel!" and took after him. Jehoshaphat yelled out, and the chariot commanders realized they had the wrong man—it wasn't the king of Israel after all. They let him go.
34Just then someone, without aiming, shot an arrow randomly into the crowd and hit the king of Israel in the chink of his armor. The king told his charioteer, "Turn back! Get me out of here—I'm wounded."
