31And his servants said to him, "Behold now, we have heard that the kings of the house of Israel are merciful kings. Let us put sackcloth around our waists and ropes on our heads and go out to the king of Israel. Perhaps he will spare your life."

32So they tied sackcloth around their waists and put ropes on their heads and went to the king of Israel and said, "Your servant Ben-hadad says, 'Please, let me live.'" And he said, "Does he still live? He is my brother."
