1 Kings 20:39
As the king passed by, the prophet called out to him, "I, your servant, went into the middle of the battle. Suddenly a man came over to me with a prisoner. He said, 'Guard this man! If he goes missing for any reason, you will pay with your life. Or else you must pay a talent of silver.'
