The 70 weeks of Daniel

The 70 weeks in Daniel are mentioned in Daniel 9, and they refer to a prophecy of Daniel where he claims that the king of Persia will release the Jews to rebuild their Temple in Jerusalem. When he makes this decree the Jews are to begin counting, and after 70 weeks (7 year periods or 490 years) the kingdom of the Messiah will be established on earth. But something interesting would happen, at the end of the 69th week (483 years) the Messiah will be "cut off" which indicates His death. The final seven year period is suddenly thrown into the future, to the time of the end of the world. This final seven year period is described in the book of Revelation as a time of the Messiah taking back the earth. It is divided into two 3 1/2 year periods and directly in the middle is when the antichrist sets up his throne in Jerusalem and reveals himself as God. Certain portions of this final seven years are mentioned in other prophetic books of the Bible like Zechariah.
