1 Kings 20:28 in the King James Version
And there came a man of God, and spake unto the king of Israel, and said, Thus saith the LORD, Because the Syrians have said, The LORD is God of the hills, but he is not God of the valleys, therefore will I deliver all this great multitude into thine hand, and ye shall know that I am the LORD.

27 The children of Israel were mustered and given provisions, 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, “The LORD says, ‘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 deliver all this great multitude into your hand, and you shall know that I am the LORD.’”
29 They encamped opposite each other for seven days. Then on the seventh day the battle was joined; and the children of Israel killed one hundred thousand footmen of the Syrians in one day.
