The beast that you saw was, and is not, and will ascend out of the bottomless pit and go to perdition.

For they are spirits of demons, performing signs, which go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.” Revelation 16:12-14.
“Then I [he] stood on the sand of the sea. And I saw a beast rising up out of the sea, having seven heads and ten horns, and on his horns ten crowns, and on his heads a blasphemous name.” Revelation 13:1.
