26 In the spring Ben-hadad mustered the Arameans and went up to Aphek to fight against Israel. 27 After the Israelites had been mustered and provisioned, they went out to engage them; the people of Israel encamped opposite them like two little flocks of goats, while the Arameans filled the country. 28 A man of God approached and said to the king of Israel, "Thus says the Lord: Because the Arameans 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 They encamped opposite one another seven days. Then on the seventh day the battle began; the Israelites killed one hundred thousand Aramean foot soldiers in one day. 30 The rest fled into the city of Aphek; and the wall fell on twenty-seven thousand men that were left. Ben-hadad also fled, and entered the city to hide.

(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.
