Parashas Eikev · Passuk 10:14
Mark, the heavens to their uttermost reachesdto their uttermost reaches Lit. “and the heaven of heavens.” belong to the ETERNAL your God, the earth and all that is on it!
Torah Temimah points to Chagigah 12b.
TT lemma: השמים ושמי השמים.
English: It was taught: R’ Yehudah said: There are two firmaments, as it is said, “Behold, to Hashem your God belong the heavens and the heavens of the heavens.”
Dispute / harmonization (two vs. seven firmaments)
The doubled language of heavens supports either a two-level or a seven-level cosmology depending on how one counts.
