1KI 20:39

39 When the king passed by, the prophet cried out to him, saying “Your majesty, [after I was wounded] while I was fighting in a battle, a soldier brought to me one of our enemies that he had captured, and said to me, ‘Guard this man! If he escapes, you must pay me 3,000 pieces of silver, and if you do not pay that, you will be executed!’
