1 Kings 20:30-32

30But the rest ran to the city of Aphek, and the [city] wall fell on 27,000 of the men who were left. Ben-hadad escaped and came into the city, going into an inner chamber [to hide].

31But his servants said to him, “We have heard that the kings of the house (royal line) of Israel are merciful kings. Please let us put sackcloth around our loins and ropes on our necks [as symbols of submission], and go out to the king of Israel; perhaps he will spare your life.”

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