1 Kings 20:39-42

39As the king passed by, the prophet called out to him, “Your servant went into the thick of the battle, and someone came to me with a captive and said, ‘Guard this man. If he is missing, it will be your life for his life, or you must pay a talent That is, about 75 pounds or about 34 kilograms of silver.’

40While your servant was busy here and there, the man disappeared.” “That is your sentence,” the king of Israel said. “You have pronounced it yourself.” 41Then the prophet quickly removed the headband from his eyes, and the king of Israel recognized him as one of the prophets. 42He said to the king, “This is what the LORD says: ‘You have set free a man I had determined should die. The Hebrew term refers to the irrevocable giving over of things or persons to the Lord, often by totally destroying them. Therefore it is your life for his life, your people for his people.’ ”
