Isang ilog ng apoy ang umaagos at lumalabas mula sa harap niya. Libu-libong libo ang naglilingkod sa kanya, at sampung libong ulit ng sampung libo ang nakatayo sa harap niya. Umupo ang hukuman, at binuksan ang mga aklat.
Kitzur Ba'al HaTurim
ושוב "and again" 3 separate Tanakh places; And the rest which went forth to and fro, until the waters were dried up from off the earth(Gen 8:7). And the living creatures ran and returned (Ezek 1:14). It is he who said that the fear of the animals comes out like A fiery stream issued and came forth from before him (Daniel 7:10).
Rabbeinu Bahya
You should also know that the period of time that Torah preceded creation of the universe until the directive of “let there be light,” has also been hinted at in the word ב-ראשית. The letter ב in that word alludes to the two thousand years Torah preceded our universe, a period called “beginning,” i.e. ראשית.
We find some proof of this in the Bereshit Rabbah 3,7 which points out that the Torah did not write יהי ערב, “let there be evening,” but only ויהי ערב, “it remained evening,” i.e. there had already been a system called time, [though time was not counted in terms we are familiar with. Ed.]
We must concede that the concept of time itself was a creative act and prior to that act “time” did not exist. Nonetheless we find time prior to the creation of the universe referred to specifically in several instances throughout the Bible. When the sages spoke about “two thousand years” which the Torah preceded the universe they did not refer to days or years in the manner we count days or years nowadays. The element of “time” in that context is not subject to investigation by the human intellect. Job 36,26 referred to this phenomenon when he wrote הן קל שגיא ולא נדע מספר שניו ולא חקר; “Here G’d is greater than we can know; the number of His years cannot be counted.” Another reference to this kind of time is found in Job 10,8 הן כ-ימי אנוש ימיך , “are Your days to be compared to human days?” or Psalms 102,28 ימי שנותיך לא יתמו, “the days of Your years are never ending.” During those “times,” it occurred to G’d to creative 1000 generations (of human history); however 974 of these generations were wiped out (compare Chagigah 13-14). This means that these 974 generations were “wiped out” from G’d’s original plan. They had not ever been created in the flesh. As a result of these 974 generations never having seen the light of day the Torah was given to the Jewish people after man existed for 26 generations. The reason G’d reconsidered His original plan was that He foresaw that the people in those generations would all be wicked. G’d advanced the giving of the Torah so that He would thereby advance the cycle that would otherwise have taken 1000 generations. This is the meaning of Psalms 105,8 “He is ever mindful of His covenant, the promise He gave for a thousand generations.” The words “for a thousand generations” mean: “at the end of one thousand generations.” These “lost “ generations are referred to by our sages in Chagigah 13 when they quoted Daniel 7,10 נהר דינור נגיד ונפיק מן קדמוהי אלף אלפין ישמשונה ורבו רבבן קדמוהי יקומון דינא יתיב וספרין פתיחו, “A river of fire streamed before Him; thousands upon thousands served Him; myriads upon myriads attended Him; the court sat and the books were opened.” The Talmud asks” “whence did the river originate?’ The answer given is that it was the result of the sweat of the beasts. To the question where this river Dinor ended, the answer given is “on the heads of the wicked in hades,” seeing that we have a verse in Job 22,1 אשר קמטו ולא עת נהר יוצק יסודם; “how they have shrivelled up before their time, and their foundation poured out like a river.” Rabbi Acha bar Yaakov interpreted the first half of this verse as describing G’d’s anger. Rabbi Shimon ben Chasidah understands this verse as a reference to the 974 generations which had originally been planned by G’d to come into existence prior to the universe as we know it. What did G’d do with them? He suspended them in that river. Some appear in each generation and they are the ones whose main purpose in life is to mock G’d. Thus far the discussion in Chagigah.

Or HaChaim
Still another meaning of the comparison drawn by the composer of this song is based on Daniel 7,10 where the waters of the mythical river Dinor are described as the product of the sweat of the Chayot [permanent kind of angels Ed.] which proclaim the holiness of G'd and to whom this is an awe-inspiring experience, i.e. נאדר בקודש (compare Chagigah 13).
Rashi
your windows Jonathan renders: your woodwork, and Menahem associated it with (Dan. 7:10): “ministered to Him (יְשַׁמְּשׁוּנֵהּ).” (Menahem, apparently renders: your utensils, i.e., the vessels that serve you.) And some interpret it as an expression of a sun (שֶׁמֶשׁ), windows through which the sun shines, and they make opposite it a barrier of kinds of colored glass for beauty, and Midrash Psalms interprets שִׁמְשׁוֹתַיִךְ as well as שֶׁמֶשׁ וּמָגֵן (Ps. 84:12) as “the pinnacles of the wall.”
