Isaiah 31:6-9

Turn ye unto him from whom the children of Israel have deeply revolted. For in that day every man shall cast away his idols of silver, and his idols of gold, which your own hands have made unto you for a sin. Then shall the Assyrian fall with the sword, not of a mighty man; and the sword, not of a mean man, shall devour him: but he shall flee from the sword, and his young men shall be discomfited. And he shall pass over to his strong hold for fear, and his princes shall be afraid of the ensign, saith the LORD, whose fire is in Zion, and his furnace in Jerusalem.
