Daniel
From Memory Alpha, the free Star Trek reference
Daniel was a biblical figure in ancient Human history who was once placed in a lion's den for refusing to worship a Babylonian king as a god.
Leonard McCoy referred to Daniel's banishment to "the lion's den" when he learned of Captain Kirk was being held prisoner by the Providers of Triskelion, then he noted that the Commander Spock would need a medical officer.
Spock recalled that Daniel had "only his faith" during his imprisonment, but that he welcomed the doctor's company just the same. (TOS: "The Gamesters of Triskelion")
