Isaiah 30:29-31

New Century Version

²⁹ 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.
³⁰ 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.
³¹ Assyria will be afraid when it hears the voice of the Lord,
    because he will strike Assyria with a rod.
