1 Kings 20:31-33

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.”

33Now the men took it as a good omen, and quickly understanding his meaning said, “Yes, your brother Ben-hadad lives.” Then the king said, “Go, bring him.” Then Ben-hadad came out to him, and Ahab had him come up into the chariot.
