1 Kings 20:27-28

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.’”
