26 And it came to pass at the return of the year, that Ben-hadad mustered the Syrians, and went up to Aphek, to fight against Israel. 27 And the children of Israel were mustered, and were victualled, and went against them: and the children of Israel encamped before them like two little flocks of kids; but the Syrians filled the country. 28 And a man of God came near and spake unto the king of Israel, and said, Thus saith Jehovah, Because the Syrians have said, Jehovah is a god of the hills, but he is not a god of the valleys; therefore will I deliver all this great multitude into thy hand, and ye shall know that I am Jehovah. 29 And they encamped one over against the other seven days. And so it was, that in the seventh day the battle was joined; and the children of Israel slew of the Syrians a hundred thousand footmen in one day. 30 But the rest fled to Aphek, into the city; and the wall fell upon twenty and seven thousand men that were left. And Ben-hadad fled, and came into the city, into an inner chamber.

(Read 1 Kings 20:22-30)

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.
