Dan 3:24

“Verses 24-25. "Then Nebuchadnezzar the king was astounded and hastily arose and said to his nobles: 'Did we not cast three men in shackles into the midst of the fire?'" After the princes have been punished, the king is rebuked, in order that he may glorify God while still alive. But he questions his nobles, by whose accusation and plot he had cast the three youths into the fiery furnace, so that when they reply that they had cast three youths into the furnace, he might announce and show forth to them (what had happened). "And they said to the king in reply, 'Truly, O king!' The king answered (the Vulgate omits "the king"): 'Behold, I see four men unbound and walking about in the midst of the fire, and they have no hurt, and the appearance of the fourth man is the likeness of a son of God.'" Let me say again, how wise was the fire and how indescribable the power of God! Their bodies had been bound with chains; those chains were burnt up, whereas the bodies themselves were not burnt. As for the appearance of the fourth man, which he asserts to be like that of a son of God, either we must take him to be an angel, as the Septuagint has rendered it, or indeed, as the majority think, the Lord our Savior. Yet I do not know how an ungodly king could have merited a vision of the Son of God. On that reasoning one should follow Symmachus, who has thus interpreted it: "But the appearance of the fourth is like unto the sons," not unto the sons of God but unto gods themselves. We are to think of angels here, who after all are very frequently called gods as well as sons of God. So much for the story itself. But as for its typical significance, this angel or son of God foreshadows our Lord Jesus Christ, who descended into the furnace of hell (Ephesians 4:9, 1 Peter 4:6), in which the souls of both sinners and of the righteous were imprisoned, in order that He might without suffering any scorching by fire or injury to His person deliver those who were held imprisoned by chains of death.”
