During king Jehoiakim's reign in Judah,
before Judah was destroyed,
King Nebuchadnezzar of Babylon attacked Judah
and took some treasures and
some of the young men of Judah as captives.
As for the captives,
King Nubuchadnezzar ordered his officials
to select strong, healthy, and good-looking young men
to have them serve in the royal court.
Daniel, Hananiah, Mishael, and Azariah were 4 of the young men chosen.
They were to have the best food and wine,
and to be trained for 3 year period.
But Daniel and his 3 friends made up their mind
not to defile themselves by eating
the food and wine given them by the king.
The official was worried that the king might punish him
for not having them eat the best food.
So Daniel suggested him to test them
for 10 days on a diet of vegetables and water only.
After 10 days, Daniel and his 3 friends looked
healthier than other who had been eating the food given by the king.
God also gave Daniel and his friends
wisdom and uncanny abilities for learning
the literature and science of the time.
God especially gave Daniel
an ability in understanding the meanings of
visions and dreams.
After 3 years of training,
Daniel and his 3 friends were selected
to be king's staff of advisers.
