1 Kings 20:13-14

13Meanwhile a prophet came to Ahab king of Israel and announced, “This is what the Lord says: ‘Do you see this vast army? I will give it into your hand today, and then you will know that I am the Lord.’ ”

14“But who will do this?” asked Ahab. The prophet replied, “This is what the Lord says: ‘The junior officers under the provincial commanders will do it.’ ” “And who will start the battle?” he asked. The prophet answered, “You will.”
