1st Kings 20:38

35 A certain man of the sons of the prophets said to his fellow by the word of Yahweh, Please strike me. The man refused to strike him.

36 Then said he to him, Because you have not obeyed the voice of Yahweh, behold, as soon as you are departed from me, a lion shall kill you. As soon as he was departed from him, a lion found him, and killed him.

37 Then he found another man, and said, Please strike me. The man struck him, smiting and wounding him.

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

39 As the king passed by, he cried to the king; and he 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, Keep this man: if by any means he be missing, then shall your life be for his life, or else you shall pay a talent of silver.

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

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