Isaiah 30:29-32

You will sing happy songs as on the nights you begin a festival. You will be happy like people listening to flutes as they come to the mountain of the LORD, to the Rock of Israel. The LORD will cause all people to hear his great voice and to see his powerful arm come down with anger, like a great fire that burns everything, like a great storm with much rain and hail. Assyria will be afraid when it hears the voice of the LORD, because he will strike Assyria with a rod. When the LORD punishes Assyria with a rod, he will beat them to the music of tambourines and harps; he will fight against them with his mighty weapons.
