1 Kings 20:35

31 Then the servants of Ben-hadad said to him, “Look now, we have heard that the kings of the house of Israel are merciful. Let us go out to the king of Israel with sackcloth around our waists and ropes around our heads. Perhaps he will spare your life.”

32 So with sackcloth around their waists and ropes around their heads, they went to the king of Israel and said, “Your servant Ben-hadad says, ‘Please spare my life.’” And the king answered, “Is he still alive? He is my brother.”

33 Now the men were looking for a sign of hope, and they quickly grasped at this word and replied, “Yes, your brother Ben-hadad.” “Go and get him!” said the king. Then Ben-hadad came out, and Ahab had him come up into his chariot.

34 Ben-hadad said to him, “I will restore the cities my father took from your father; you may set up your own marketplaces in Damascus, as my father did in Samaria.” “By this treaty I release you,” Ahab replied. So he made a treaty with him and sent him away.

35 Meanwhile, by the word of the LORD, one of the sons of the prophets said to his companion, “Strike me, please!” But the man refused to strike him.

36 Then the prophet said to him, “Because you have not obeyed the voice of the LORD, as soon as you depart from me a lion will kill you.” And when he left, a lion found him and killed him.

37 Then the prophet found another man and said, “Strike me, please!” So the man struck him and wounded him,

38 and the prophet went and waited on the road for the king, disguising himself with a bandage over his eyes.

39 As the king passed by, he cried out to the king: “Your servant had marched out into the middle of the battle, when suddenly a man came over with a captive and told me, ‘Guard this man! If he goes missing for any reason, your life will be exchanged for his life, or you will weigh out a talent of silver.’
