1 Kings 20:30-32

30The rest of them fled into the city of Aphek, where the wall fell on twenty-seven thousand of the remaining men. Ben-hadad also fled to the city and hid in an inner room.

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.”
