Daniel has just seen the empire of Babylon fall, and upon meditating on the 70-year prophecy of Jeremiah, is praying to God to forgive His people, move their hearts to repentance, and restore them to Jerusalem. In this passage, God answers that prayer through the angel Gabriel. The answer to Daniel's pleas for mercy is not only restoration to Jerusalem and the rebuilding of the city, but also a Messiah who will one day come and make a soul-saving covenant through his death. To put it more explicitly, the answer to Daniel's prayer for forgiveness is the person - new covenant work of Jesus Christ, and the end of the old covenant.
