Isaiah 30:29-32

Ye shall have a song as in the night when a holy feast is kept; and gladness of heart, as when one goeth with a pipe to come unto the mountain of Jehovah, to the Rock of Israel. And Jehovah will cause his glorious voice to be heard, and will show the lighting down of his arm, with the indignation of his anger, and the flame of a devouring fire, with a blast, and tempest, and hailstones. For through the voice of Jehovah shall the Assyrian be dismayed; with his rod will he smite him. And every stroke of the appointed staff, which Jehovah shall lay upon him, shall be with the sound of tabrets and harps; and in battles with the brandishing of his arm will he fight with them.
