Isaiah 30:29-32

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. At the LORD’s command, the Assyrians will be shattered. He will strike them down with his royal scepter. And as the LORD strikes them with his rod of punishment, his people will celebrate with tambourines and harps. Lifting his mighty arm, he will fight the Assyrians.
