Daniel 7:6-7, 23

After that, as I looked on, behold, there was another one that looked like a tiger. On its back were four large wings of a bird. This beast had four heads, and it was given authority for dominion. Then in my night vision, behold, I saw a fourth beast! It was dreadful, terrifying, and incredibly powerful. It had huge iron teeth used for crushing and devouring its victims. With its massive feet it trampled on what was left. It had ten horns and was totally different from the other beasts.

He gave me the interpretation: “The fourth beast means that there will be a fourth kingdom on the earth, different from all the other kingdoms. It will devour the whole earth, trample it down, and shatter it to pieces.
