Why does it say again "b'Chezvei Leilya"?
Malbim: This was a new vision. Also now he saw with night, for Galus will continue to darken when dawn begins to illuminate and breaks through the dark clouds.
What is the significance of "Ananei Shemaya"?
Malbim: The Chayos came from the depth of the sea below. Malchus Shamayim comes from clouds above. Clouds are fine vapors full of light Ru'ach. They rise from the sea and give rain. So Mashi'ach's coming will be via spiritual Tal (dew) that rises via his Torah and deeds, which are elevated above physicality ? "Ki Tal Oros Talecha."
Which man came?
Rashi, Ibn Ezra (14, citing R. Yeshu'ah): Melech ha'Mashi'ach. Malbim ? the kingdoms were depicted as Chayos, for they made wars and tore people and consumed them. Malchus Hashem will come via understanding Toras Hashem and doing his Mitzvos. This is attributed to an intelligent person. He is depicted as "Oni v'Rochev Al ha'Chamor" ? he will subdue physicality.
Ibn Ezra (14): It is Am ha'Kadosh ? Yisrael.
What was he doing "Ad Atik Yomaya"?
Rashi: He was judging the Goyim.
Malbim: Via his deeds and preparation, he will approach Elokim, and then Divine help will bring him close to Elokim ? "Yedaticha ba'Shem v'Gam Matzasa Chen b'Einai."
