Revelation 16:10

So Moses stretched out his hand toward the sky, and there was thick darkness in all the land of Egypt for three days.

And the beast which I saw was like a leopard, and his feet were like those of a bear, and his mouth like the mouth of a lion. And the dragon gave him his power and his throne and great authority.

Then I heard a loud voice from the sanctuary, saying to the seven angels, “Go and pour out on the earth the seven bowls of the wrath of God.”

I bear witness to everyone who hears the words of the prophecy of this book: If anyone adds to them, God will add to him the plagues which are written in this book.
