Daniel 3:25 - Ellicott's Commentary On The Whole Bible

The Son of God. — These words, let us remember, are uttered by a heathen king, who calls this same Person, in Daniel 3:28, “an angel” of the God whom the three children worshipped. Probably Nebuchadnezzar thought that He stood to Jehovah in the same relation that he himself did to Merodach. His conceptions of the power of Jehovah were evidently raised by what he had witnessed, though as yet he does not recognise Him as being more than a chief among gods. He has not risen to that conception of the unity of God which is essential to His absolute supremacy. But still the question has to be answered, What did the king see? The early Patristic interpretation was that. it was none other than Christ Himself. We have no means of ascertaining anything further, and must be content with knowing that the same “Angel of God’s presence” who was with Israel in the wilderness watched over the people in Babylon.
