'Thunders' in the Bible

And cried with a loud voice, as when a lion roareth: and when he had cried, seven thunders uttered their voices.

And when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not.

And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great.
