The dream of Babylonian king Nebuchadnezzar and other visions foretold of four great kingdoms (Babylon, Medo-Persia, Greece, and Rome), the last of which would be overtaken by the kingdom of God, which would rule over the whole earth. The Medo-Persians conquered Babylon in 539 B.C. Daniel has a vision of the heavenly "Son of Man" who will rule over all nations. The "70 weeks" of chapter 9 predict that the Messiah will appear near 32 A.D. and will be "cut off." Daniel sees a vision of the final judgment and end of days.
