Isaiah 30:29-30

But the people of God will sing a song of joy, like the songs at the holy festivals. You will be filled with joy, as when a flutist leads a group of pilgrims to Jerusalem, the mountain of the LORD— to the Rock of Israel. And the LORD will make his majestic voice heard. He will display the strength of his mighty arm. It will descend with devouring flames, with cloudbursts, thunderstorms, and huge hailstones.
