Revelation 13:1 - 4
ESV - 1 And I saw a beast rising out of the sea, with ten horns and seven heads, with ten diadems on its horns and blasphemous names on its heads. 2 And the beast that I saw was like a leopard; its feet were like a bear's, and its mouth was like a lion's mouth. And to it the dragon gave his power and his throne and great authority.
