While the best known Daniel is the hero of the Book of Daniel who interprets dreams and receives apocalyptic visions, the Bible also briefly mentions three other individuals of this name:
Daniel, whose name means “God is my judge,” and his three countrymen from Judea were chosen and given new names. Daniel became “Belteshazzar,” while Hananiah, Mishael, and Azariah became “Shadrach," "Meshach," and "Abednego.”
The book contains traditional stories (chaps. 1 – 6), which tell of the trials and triumphs of the wise Daniel and his three companions. The moral is that people of faith can resist temptation and conquer adversity.
