1 Kings 20:28-30

And a man of God came near and spake unto the king of Israel, and said, Thus saith Jehovah, Because the Syrians have said, Jehovah is a god of the hills, but he is not a god of the valleys; therefore will I deliver all this great multitude into thy hand, and ye shall know that I am Jehovah. And they encamped one over against the other seven days. And so it was, that in the seventh day the battle was joined; and the children of Israel slew of the Syrians a hundred thousand footmen in one day. But the rest fled to Aphek, into the city; and the wall fell upon twenty and seven thousand men that were left. And Ben-hadad fled, and came into the city, into an inner chamber.
