1 Kings 20:31-33

31Then 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.”

32So 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.”

33Now 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.
