1 Kings 20:28-30

New Revised Standard Version, Anglicised

²⁸ A man of God approached and said to the king of Israel, ‘Thus says the Lord: Because the Arameans have said, “The Lord is a god of the hills but he is not a god of the valleys”, therefore I will give all this great multitude into your hand, and you shall know that I am the Lord.’ ²⁹ They encamped opposite one another for seven days. Then on the seventh day the battle began; the Israelites killed one hundred thousand Aramean foot-soldiers in one day. ³⁰ The rest fled into the city of Aphek; and the wall fell on twenty-seven thousand men that were left.

Ben-hadad also fled, and entered the city to hide.
