1 Kings 20:27-31

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.

But his servants said to him, “Behold now, we have heard that the kings of the house of Israel are merciful kings. Please let’s put sackcloth around our waists and ropes on our heads, and go out to the king of Israel; perhaps he will let you live.”
