28Then the man of God approached the king of Israel and said, “This is what the LORD says: ‘Because the Arameans think the LORD is a god of the hills and not of the valleys, I will deliver all this great army into your hand. Then you will know that I am the LORD.’”
29For seven days the armies camped opposite each other, and on the seventh day the battle ensued, and the Israelites struck down the Arameans— a hundred thousand foot soldiers in one day.
30The rest of them fled into the city of Aphek, where the wall fell on twenty-seven thousand of the remaining men. Ben-hadad also fled to the city and hid in an inner room.
