The Prophet Daniel and the Three Children were all descended from the royal tribe of Judah. In the year 599 before Christ, in the reign of Joachim, (I Chron. 3:16, and II Chron. 36:8), while yet children, these righteous ones were led away as captives into Babylon together with the other Jews by Nebakanezer. He singled them out from among the other captives to serve him, and renamed them. They were reared in the royal court, and taught the wisdom of the Chaldeans; and after the passage of three years, they surpassed all the Chaldean sages (Dan. 1).
Daniel had courage. When a decree was made that no one was to worship or ask anything from God, Daniel never stopped supplicating God, fasting and praying on his knees three times a day. Because of this prayer he was cast into the den of lions. By having stopped the mouths of the lions by divine might, and appearing among them as though he were a shepherd of sheep, Daniel showed the might of godliness (Daniel 6:1-23). This level of trust, sanity and sanctity is available to us as well!
