What are "Asaya v'Simhaya"?
Ibn Ezra: They are signs and wonders ? a person is Tame'ah (astonished) from them, for he never saw like them.
Malbim: Osos are ways within nature of clarifying that He oversees, e.g. prophecy of future events, e.g. his dream. Mofesim are wonders that change nature, e.g. Hashem made Nebuchadnetzar an animal, and returned him to his kingship.
What do we learn from "Di Avad Imi Elaka Ila'ah?
Malbim: Nebuchadnetzar admitted to Hashgachah Pratis, and that Hashem's acts are by Himself without an intermediary, even though He is Kel Elyon.
What is the meaning of "Shefar Kadamai Lehachavayah"?
Rashi: It is good for me to tell. Ibn Ezra ? Shefar is like "ha'Nosen Imrei Shefer."
Why did Nebuchadnetzar want to tell all this?
Malbim: Initially, he denied Hashgachah and Chidush ha'Olam. He held that everything is forced to be due to causes, and Hashem cannot change nature and the Ma'arachah. He denied wonders via overriding nature. He held that Hashem handed over conduct of the world to officers of the Ma'arachah, so they served them. The image was based on astrology and service of the stars, to make the gold kingdom rule over all for all generations. He was punished for this. Therefore, after he recognized Hashem's power, he wanted to fix his sin via informing all nations of the power of the Creator.
