King Nebuchadnezzar's Defeat Of Jerusalem

In this introduction to Daniel we read briefly of the account of King Nebuchadnezzar’s siege and defeat of Jerusalem and how he captures the people and takes them back to Babylon. Daniel and his friends are chosen to serve in Nebuchadnezzar’s court, there they refuse to eat the Kings “delicacies” (one of the privileges of been in the Kings court) instead they persuade the guard in charge of them to feed them vegetables instead (Daniel fast).
At the appointed time (3 years ) they are brought before Nebuchadnezzar and Daniel and his friends impress the king far more than any other the other young men. They entered into the Royal service of the King. They became advisors to the King. They entered into politics.
