1 Kings 20:29-30
29-30The two armies were poised in a standoff for seven days. On the seventh day fighting broke out. The Israelites killed 100,000 of the Aramean infantry in one day. The rest of the army ran for their lives back to the city, Aphek, only to have the city wall fall on 27,000 of the survivors.
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."
