26 In the spring Ben-ha'dad mustered the Syrians, and went up to Aphek, to fight against Israel. 27 And the people of Israel were mustered, and were provisioned, and went against them; the people of Israel encamped before them like two little flocks of goats, but the Syrians filled the country. 28 And a man of God came near and said to the king of Israel, "Thus says the Lord, 'Because the Syrians 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 And they encamped opposite one another seven days. Then on the seventh day the battle was joined; and the people of Israel smote of the Syrians a hundred thousand foot soldiers in one day. 30 And the rest fled into the city of Aphek; and the wall fell upon twenty-seven thousand men that were left. Ben-ha'dad also fled, and entered an inner chamber in the city.

Those about Benhadad advised him to change his ground. They take it for granted that it was not Israel, but Israel's gods, that beat them; but they speak very ignorantly of Jehovah. They supposed that Israel had many gods, to whom they ascribed limited power within a certain district; thus vain were the Gentiles in their imaginations concerning God. The greatest wisdom in worldly concerns is often united with the most contemptible folly in the things of God.
