1 Kings 20:26-30

26So it was, in the spring of the year, that Ben-Hadad mustered the Syrians and went up to Aphek to fight against Israel.

27And the children of Israel were mustered and given provisions, and they went against them. Now the children of Israel encamped before them like two little flocks of goats, while the Syrians filled the countryside.

28Then a man of God came and spoke to the king of Israel, and said, “Thus says the Lord: ‘Because the Syrians have said, “The Lord is God of the hills, but He is not God of the valleys,” therefore I will deliver all this great multitude into your hand, and you shall know that I am the Lord.’ ”

29And they encamped opposite each other for seven days. So it was that on the seventh day the battle was joined; and the children of Israel killed one hundred thousand foot soldiers of the Syrians in one day.

30But the rest fled to Aphek, into the city; then a wall fell on twenty-seven thousand of the men who were left. And Ben-Hadad fled and went into the city, into an inner chamber.
