1 Kings 20:26-30

So at the turn of the year Ben-hadad mustered the Arameans and went up to Aphek to fight against Israel.

And the sons of Israel were mustered and given provisions, and they went to meet them; and the sons of Israel camped opposite them like two little flocks of goats, while the Arameans filled the country.

Then a man of God approached and spoke to the king of Israel, and said, “This is what the Lord says: ‘Since the Arameans have said, “The Lord is a god of mountains, but He is not a god of valleys,” therefore I will hand over to you all this great multitude, and you shall know that I am the Lord.’ ”

So they camped, one opposite the other, for seven days. And on the seventh day the battle was joined, and the sons of Israel killed of the Arameans a hundred thousand foot soldiers in a single day.

But the rest fled to Aphek into the city, and the wall fell on twenty-seven thousand men who were left. And Ben-hadad fled and came into the city, going from one inner room to another.
