What was the story behind Daniel's name in the novel The Bronze Bow?

In Chapter 10, Daniel's grandmother is very ill and is lying on the floor of their home. Daniel regrets not telling his grandmother his true feelings about her and why he chose to leave for the mountain. Daniel begins speaking to himself and reminiscing about old times. He tells his grandmother that she was the first person who told him the story of the prophet Daniel, who he was named after. Daniel refused to stop praying to his God, and King Darius cast him into a den of lions. God sent an angel to shut the mouths of the lions so that they would not harm Daniel. Sure enough, Daniel was not hurt while he was in the den. Daniel tells his grandmother that he enjoyed listening to the old stories and that they made him fell proud about being named Daniel.
