Daniel's First Vision: The Four Beasts, Part 2

Daniel 7

Daniel chapter 2 describes Nebuchadnezzar's vision of large statue of a man, comprised of four different metals from head to toe, that is smashed in pieces by a stone that grows into a mighty mountain. Chapter 7 tells of Daniel's vision of four great and terrible beasts that arise from the sea. What is the connection between these two amazing visions that may seem to have little in common?
