'Rumbling' in the Bible

I heard a sound from heaven like the sound of cascading waters and like the rumbling of loud thunder. The sound I heard was also like harpists playing on their harps.

Then I heard something like the voice of a vast multitude, like the sound of cascading waters, and like the rumbling of loud thunder, saying:Hallelujah, because our Lord God, the Almighty,has begun to reign!
