Dan 3:23

“For the blessed Jeremiah in captivity was no less blessed, nor was Daniel, nor Ezra, nor the blessed Hananiah, Azariah, and Mishael, than if they had not fallen into captivity; for they were led into captivity in order to bring comfort to the people in their present circumstances, and to bring hope of escaping captivity. For it is the perfection of a virtuous man to sustain the fellowship of human nature with the courage of the mind, and to lead others to better things. They do not succumb to those things which seem terrible and fearful to most people, but rather, like a brave soldier, they endure the attacks of the gravest misfortunes and undergo conflicts, and like a wise helmsman, they steer the ship in the storm, avoiding shipwreck by plowing through the waves rather than by avoiding them. He is not fearful in persecution, nor softer in tortures, lest he provoke the one tormenting him: but rather like a strong athlete, who repels the one striking him, if not with slaughter, certainly with the whip of speech; who despises the tortures feared by many, saying: Their arrows have become the wounds of infants (Ps. 63:8); who, even when wrestling with the gravest of pains, does not present himself as pitiable; but rather shows himself like a light in a lantern, shining even amidst harsh storms and the most violent winds, and the strength of his soul cannot be extinguished. He is not soft in the face of injuries to his own, nor anxious about the tomb of his body, to which he knows heaven is owed; he is not more degraded in the captivity of the civic commoners; but like a strict judge, condemning the faithlessness and errors of the infidels, like Daniel who exposed the thefts of the priests and refuted their superstitions, showing that they were not based on any truth, but were overshadowed by deceit. Such a man is truly perfect, who desires to do good to all and for nothing bad to happen to anyone; and if anything happens against his will, he himself does not lose anything of his own happiness.”

“Verse 23. "But these three men, (here the Vulgate inserts: "that is,") Shadrach, Meshach, and Abednego, fell fettered into the midst of the furnace of flaming fire. And they were walking about in the midst of the flames praising God and blessing the Lord. And Azariah stood and prayed after this fashion, opening his mouth in the midst of the fire and saying..." It was a great miracle for men to be cast into a furnace bound and to fall headlong into the midst of the fire, only to have the bonds burn up by which they were bound, the bodies of the fettered withal remaining untouched by the timid flames. The Hebrew text goes only up to this point and the intervening passage which now follows as far as the end of the Song of the Three Youths is not contained in the Hebrew. Lest we seem to pass over it altogether, we must make a few observations.”
