Isaiah 30:29-32

But you will have a joyous song throughout the night, as one celebrating a holy, consecrated feast. You will have gladness of heart, as one celebrating to the sound of a flute and dancing up the mountain of YAHWEH, the Rock who shelters Israel! And YAHWEH will cause everyone to hear his awe-inspiring, majestic voice. He will open their eyes to see his mighty power coming down with raging anger and consuming fire! His power will descend in cloudburst, thunderstorm, and hail. And when his rod strikes the Assyrians, they will be terror-stricken by the mighty voice of Lord YAHWEH. Every stroke of YAHWEH’s punishing rod will be to the sound of cymbals and strumming harps. God himself fights them in battle with dancing!
