9 I have not referred to this history without reason, but that you may learn that whether it be the wrath of a king, or the violence of soldiers, or the envy of enemies, or captivity, or destitution, or fire, or furnace, or ten thousand terrors, nothing will avail to put to shame or terrify a righteous man. For if where the king was godless the youths were not dismayed at the tyrant's wrath, how much more ought we to be confident, having an emperor who is humane and merciful, and to express thankfulness to God for this tribulation, knowing from what has now been said, that tribulations render men more illustrious both in the presence of God and of man, if they know how to bear them with fortitude! For indeed if these had not been made slaves, we should not have known their freedom! If they had not been captives, we should not have learned their nobility of soul! If they had not been exiles from their country below, we should not have known the excellency of their citizenship above! If the earthly king had not been angry with them, we should not have known the favour with which they were regarded by the heavenly King!
