The first beast looked like a lion, but it had eagle’s wings. As I watched, its wings were torn off, and it was lifted up from the ground so it stood on two feet like a person. Then it was given a human mind. Daniel 7:4 - Modern Text Bible

(This beast represents a powerful kingdom that loses its speed and strength (wings torn off), but then is changed, becoming more human or civilized.)
