1 Kings 20:37-41 New King James Version (NKJV)

37. And he found another man, and said, “Strike me, please.” So the man struck him, inflicting a wound.

38. Then the prophet departed and waited for the king by the road, and disguised himself with a bandage over his eyes.

39. 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.’

40. 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.”

41. And he hastened to take the bandage away from his eyes; and the king of Israel recognized him as one of the prophets.
