1 Kings 20: 38 - 43
Then the prophet departed and waited for the king by the road, and disguised himself with a bandage over his eyes. Now as the king passed by, he cried out to the king and said, “Your servant went out into the midst of the battle; and there, a man came over and brought a man to me, and said, ‘Guard this man; if by any means he is missing, your life shall be for his life, or else you shall pay a talent of silver.’ While your servant was busy here and there, he was gone.”
Then the king of Israel said to him, “So shall your judgment be; you yourself have decided it.”
And he hastened to take the bandage away from his eyes; and the king of Israel recognized him as one of the prophets. Then he said to him, “Thus says the LORD: ‘Because you have let slip out of your hand a man whom I appointed to utter destruction, therefore your life shall go for his life, and your people for his people.’”
So the king of Israel went to his house sullen and displeased, and came to Samaria.
