1 Kings 20:38

34Ben Hadad said to him, “The cities which my father took from your father I will restore. You shall make streets for yourself in Damascus, as my father made in Samaria.” “I”, said Ahab, “will let you go with this covenant.” So he made a covenant with him and let him go.

35A certain man of the sons of the prophets said to his fellow by the LORD’s word, “Please strike me!” The man refused to strike him.

36Then he said to him, “Because you have not obeyed the LORD’s voice, behold, as soon as you have departed from me, a lion will kill you.” As soon as he had departed from him, a lion found him and killed him.

37Then he found another man, and said, “Please strike me.” The man struck him and wounded him.

38So the prophet departed and waited for the king by the way, and disguised himself with his headband over his eyes.

39As the king passed by, he cried to the king, and he said, “Your servant went out into the middle of the battle; and behold, a man came over and brought a man to me, and said, ‘Guard this man! If by any means he is missing, then your life shall be for his life, or else you shall pay a talent of silver.’

40As your servant was busy here and there, he was gone.” The king of Israel said to him, “So shall your judgment be. You yourself have decided it.”

41He hurried, and took the headband away from his eyes; and the king of Israel recognized that he was one of the prophets.

42He said to him, “The LORD says, ‘Because you have let go out of your hand the man whom I had devoted to destruction, therefore your life will take the place of his life, and your people take the place of his people.’”
