'Horns' in the Bible

The sixth angel sounded. I heard a voice from the horns of the golden altar which is before God,

Another sign was seen in heaven. Behold, a great red dragon, having seven heads and ten horns, and on his heads seven crowns.

Then I stood on the sand of the sea. I saw a beast coming up out of the sea, having ten horns and seven heads. On his horns were ten crowns, and on his heads, blasphemous names.

I saw another beast coming up out of the earth. He had two horns like a lamb, and he spoke like a dragon.

He carried me away in the Spirit into a wilderness. I saw a woman sitting on a scarlet-colored animal, full of blasphemous names, having seven heads and ten horns.

The angel said to me, "Why do you wonder? I will tell you the mystery of the woman, and of the beast that carries her, which has the seven heads and the ten horns.

The ten horns that you saw are ten kings who have received no kingdom as yet, but they receive authority as kings, with the beast, for one hour.

The ten horns which you saw, and the beast, these will hate the prostitute, and will make her desolate, and will make her naked, and will eat her flesh, and will burn her utterly with fire.
