'Voices' in the Bible

I saw, and I heard an eagle, flying in mid heaven, saying with a loud voice, "Woe! Woe! Woe for those who dwell on the earth, because of the other voices of the trumpets of the three angels, who are yet to sound!"

He cried with a loud voice, as a lion roars. When he cried, the seven thunders uttered their voices.

The seventh angel sounded, and great voices in heaven followed, saying, "The kingdom of the world has become the Kingdom of our Lord, and of his Christ. He will reign forever and ever!"
