1 Kings 20:27-30
20:27 When the Israelites had mustered and had received their supplies, they marched out to face them in battle. When the Israelites deployed opposite them, they were like two small flocks of goats, but the Syrians filled the land.
20:28 The prophet visited the king of Israel and said, “This is what the Lord says: ‘Because the Syrians said, “The Lord is a god of the mountains and not a god of the valleys,” I will hand over to you this entire huge army. Then you will know that I am the Lord.’”
20:29 The armies were deployed opposite each other for seven days. On the seventh day the battle began, and the Israelites killed 100,000 Syrian foot soldiers in one day.
20:30 The remaining 27,000 ran to Aphek and went into the city, but the wall fell on them. Now Ben Hadad ran into the city and hid in an inner room.
