Bel and the Dragon 1:39
37 Then Habakkuk shouted, "Daniel, Daniel! Take the food that God has sent you." 38 Daniel said, "You have remembered me, O God, and have not forsaken those who love you." 39 So Daniel got up and ate. And the angel of God immediately returned Habakkuk to his own place. 40 On the seventh day the king came to mourn for Daniel. When he came to the den he looked in, and there sat Daniel! 41 The king shouted with a loud voice, "You are great, O Lord, the God of Daniel, and there is no other besides you!"
Ambrose On the Duty of the Clergy 2.4
11 What of Aaron? When did he ever think himself more blessed than when he stood between the living and the dead, and by his presence stayed death from passing from the bodies of the dead to the lines of the living? What shall I say of the youth Daniel, who was so wise that, when in the midst of the lions enraged with hunger, he was by no means overcome with terror at the fierceness of the beasts. So free from fear was he, that he could eat, and was not afraid he might by his example excite the animals to feed on him.
Notes and References
"... The apocryphal texts are quoted by the church fathers as authoritative scripture, particularly by those who did not know Hebrew and relied on the Septuagint alone. In preparing the Vulgate, however, Jerome distinguished between biblical texts that could be used as a basis for establishing doctrine, and apocryphal texts that are edifying but not decisive from a doctrinal perspective ... Two other additions to Daniel, Bel and The Dragon, are stories that ridicule idolatry. In Bel, Daniel uncovers the artifice which made it appear that the idol Bel was consuming copious amounts of food and drink, thereby proving to Cyrus of Persia that Bel is a mere statue unworthy of worship. In The Dragon, Daniel proves that the revered dragon is mortal by feeding him a concoction of boiled pitch, fat, and hair and thereby causing the dragon to burst. As punishment, Daniel is thrown into the lion’s den, where he survives a week with God’s assistance ..."
