1 Kings 20:30-31
30-31Ben-Hadad escaped into the city and hid in a closet. Then his advisors told him, "Look, we've heard that the kings of Israel play by the rules; let's dress in old gunnysacks, carry a white flag of truce, and present ourselves to the king of Israel on the chance that he'll let you live."
32So that's what they did. They dressed in old gunnysacks and carried a white flag, and came to the king of Israel saying, "Your servant Ben-Hadad said, 'Please let me live.'"
Ahab said, "You mean to tell me that he's still alive? If he's alive, he's my brother."
