1 Kings 20:23-30 ESV
And the servants of the king of Syria said to him, “Their gods are gods of the hills, and so they were stronger than we. But let us fight against them in the plain, and surely we shall be stronger than they. And do this: remove the kings, each from his post, and put commanders in their places, and muster an army like the army that you have lost, horse for horse, and chariot for chariot. Then we will fight against them in the plain, and surely we shall be stronger than they.” And he listened to their voice and did so.
In the spring, Ben-hadad mustered the Syrians and went up to Aphek to fight against Israel. 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. 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.’” And they encamped opposite one another seven days. Then on the seventh day the battle was joined. And the people of Israel struck down of the Syrians 100,000 foot soldiers in one day. And the rest fled into the city of Aphek, and the wall fell upon 27,000 men who were left.
Ben-hadad also fled and entered an inner chamber in the city.
