John Gill Commentary Daniel 5:11

"There is a man in thy kingdom, in whom is the spirit of the holy gods; and in the days of thy father light and understanding and wisdom, like the wisdom of the gods, were found in him; and the king Nebuchadnezzar thy father, the king, [I say], thy father, made him master of the magicians, enchanters, Chaldeans, and soothsayers;" — Daniel 5:11 (ASV)

There is a man in your kingdom She does not say in his court; very probably, after the death of Nebuchadnezzar, perhaps in one of the former reigns, he was removed from his offices; for, had he been in one, very likely the queen would have described him by it; and this seems to receive confirmation by the question Belshazzar put to him upon his coming into his presence, are you that Daniel; and only says that he had heard of him, (Daniel 5:13Daniel 5:14).

in whom is the spirit of the holy gods; something divine, something more than human; she uses the very words of Nebuchadnezzar; which seems to confirm that opinion, that she was his widow, (Daniel 4:8).

and in the days of your father light and understanding and wisdom, like the wisdom of the gods, was found in him; "light" in the knowledge of things obscure; understanding in the interpretation of dreams; and "wisdom" in things both human and divine, like that of an angel of God, as Jacchiades interprets "Elohim": of this instances were given in the days of his grandfather, for so Nebuchadnezzar was; nor is it unusual for a grandfather to be called a father, and even a more remote ancestor; which instances were, telling him his dream when he had forgot it, as well as the interpretation of it; and explaining his dream or vision of the tree cut down to its stump; of which see Daniel chapters two and four.

whom the king Nebuchadnezzar your father, the king, I say, your father, made master of the magicians, astrologers, Chaldeans, and soothsayers, (Daniel 2:48) she seems tacitly to upbraid him with his neglect of such a man, or with turning him out of his office, when so great a prince as his grandfather was took so much notice of him, and so highly advanced him.
