22 The prophet came near to the king of Israel, and said to him, “Go, strengthen yourself, and mark, and see what you do; for at the return of the year the king of Syria will come up against you.” 23 The servants of the king of Syria said to him, “Their god is a god of the hills; therefore they were stronger than we. But let us fight against them in the plain, and surely we shall be stronger than they. 24 Do this thing: take the kings away, every man out of his place, and put captains in their place. 25 Muster an army, like the army that you have lost, horse for horse, and chariot for chariot. We will fight against them in the plain, and surely we will be stronger than them.”

He listened to their voice, and did so. 26 It happened at the return of the year, that Ben Hadad mustered the Syrians, and went up to Aphek, to fight against Israel. 27 The children of Israel were mustered, and were provisioned, and went against them. The children of Israel encamped before them like two little flocks of young goats; but the Syrians filled the country. 28 A man of God came near and spoke to the king of Israel, and said, “Thus says Yahweh, ‘Because the Syrians have said, “Yahweh is a god of the hills, but he is not a god of the valleys;” therefore I will deliver all this great multitude into your hand, and you shall know that I am Yahweh.’” 29 They encamped one over against the other seven days. So it was, that in the seventh day the battle was joined; and the children of Israel killed one hundred thousand footmen of the Syrians in one day. 30 But the rest fled to Aphek, into the city; and the wall fell on twenty-seven thousand men who were left. 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.
