1 Kings 20:37-41

Then he found another man and said, “Please strike me.” And the man struck him, injuring him.

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

And as the king passed by, he cried out to the king and said, “Your servant went out into the midst of the battle; and behold, a man turned aside and brought a man to me and said, ‘Guard this man; if for any reason he goes missing, then your life shall be forfeited in place of his life, or else you shall pay a talent of silver.’

Now while your servant was busy here and there, he disappeared.” And the king of Israel said to him, “So shall your judgment be; you yourself determined it.”

Then he quickly took the bandage away from his eyes, and the king of Israel recognized him, that he was one of the prophets.
