1st Kings 20:40

37 Then he came across another man, and said, Give me a wound. And the man gave him a blow wounding him.

38 So the prophet went away, and pulling his head-band over his eyes to keep his face covered, took his place by the road waiting for the king.

39 And when the king went by, crying out to him he said, Your servant went out into the fight; and a man came out to me with another man and said, Keep this man: if by any chance he gets away, your life will be the price of his life, or you will have to give a talent of silver in payment.

40 But while your servant was turning this way and that, he was gone. Then the king of Israel said to him, You are responsible; you have given the decision against yourself.

41 Then he quickly took the head-band from his eyes; and the king of Israel saw that he was one of the prophets.

42 And he said to him, These are the words of the Lord: Because you have let go from your hands the man whom I had put to the curse, your life will be taken for his life, and your people for his people.

43 Then the king of Israel went back to his house, bitter and angry, and came to Samaria.
