What does 1 Kings 20:32 mean?

So they put on rough clothes and tied ropes around their waists, then went to the king of Israel and said, 'Your servant Ben-Hadad is asking for mercy.' Ahab answered, 'Is he still alive? He’s my brother.' 1 Kings 20:32 - Modern Text Bible

(Ben-Hadad’s men approach Ahab humbly, hoping for mercy. Ahab’s response is surprisingly generous, calling Ben-Hadad his 'brother,' signaling he’s open to reconciliation.)
