1 Kings 20:31-32

31Then his servants said to him, “Look now, we have heard that the kings of the house of Israel are merciful kings. Please, let us put sackcloth around our waists and ropes around our heads, and go out to the king of Israel; perhaps he will spare your life.”

32So they wore sackcloth around their waists and put ropes around their heads, and came to the king of Israel and said, “Your servant Ben-Hadad says, ‘Please let me live.’ ” And he said, “Is he still alive? He is my brother.”
