ברוך שכחו מלא עולם – And if he desires, he should recite the blessing, “Praised [are You God] who is the Author of Creation” for all of these are acts of creation as it is written (Psalms 135:7), “[He makes clouds rise from the end of the earth;] He makes lightning for the rain ; [He releases the wind from His vaults],”but on the mountains and on the hills, etc., one says, “Who is the Author of Creation, specifically, but he is not able to make the blessing on them, “that His power fills the world” which are not seen in most of the world, but rather each and every person [recites the blessing] in his place.
Shadal
"Let there be a firmament:" The Holy One, blessed be He, wanted to inform Israel that neither the sun nor anything else controls the rain, to bring it down or not to bring it down. Therefore, He told about the existence of the higher waters before the existence of the luminaries. "Firmament (rakiya):" [It is] a body that stretches out like a plate, [as in] the expression, "To the One that stretches out (rokea) the earth over the waters" (Psalms 136:6); "And they flattened (yiraka'au) the gold [into thin plates]" (Exodus 39:3); and [also] "And over the heads of the living creatures there was the likeness of a firmament, like the color of the terrible ice" (Ezekiel 1:22). And here it portrayed the air between the earth and the clouds as a body that extends and separates between the waters on earth and the waters in the clouds, and carries the waters upon it; and by the will of God, the water descends from there to the earth. And it is like it states (Deuteronomy 28:12), "And God will open for you His good storehouse, the heavens, to give the rain of your land in its time;" and in the Curse, when it states (Leviticus 26:19), "And I will give your skies to be like iron," to prevent the descent of water upon them; and so [too] below (Genesis 7:11), "and the windows of the heavens opened." But afterwards, in the time of Yishiyahu, it appears that they knew that there are no storehouses of water above, and that rain waters return above; since behold, he says (Isaiah 55:10), "For just as the rain and the snow come down from the skies, and do not return there except when the earth is satiated;" [which] implies that after it is satiated, it does return to there, see my commentary there. And so [too], Yirmiyahu said in the way of a question, "do the heavens give raindrops?" (Jeremiah 14:22); [which] implies that [the heavens] do not give them by themselves, since they do not have storehouses of water in them. And so [too], they called the vapors that rise up from upon the earth [and become clouds] the name, nissi'im (raised up ones), as [in], "He raises nissi'im from the end of the earth" (Psalms 135:7); "He raised the nissi'im from the end of the earth" (Jeremiah 10:13; 51:16); and so [too], "Nissi'im and wind, but no rain" (Proverbs 25:14). And we do not know from what time this word (nissi'im) became common; as Psalm 135 is not attributed to David and it is not clear that the Book of Proverbs from Chapter 25 is by Shlomo. And in Job, he says (Job 38:22), "Did you come to the storehouses of snow, did you see the storehouses of hail?" - and this is a proof of the antiquity of that book. And since the word, rakiya, is based on the belief in higher waters - "the waters that are above the heavens" (Psalms 148:4) - that the rakiya supports, and that belief became antiquated and forgotten; the word, rakiya, also became antiquated. And [rakiya] is only used to indicate the skies in three [other] places. Two are in Psalms - "and the acts of your hands, does the rakiya proclaim" (Psalms 19:2); "praise Him in the rakiya of His strength" (Psalms 150:1) - since the word remained in poetic use; as it is the custom in all languages for the poets to use antiquated words. And the third place is in Daniel 12:3, "And the enlightened ones will shine like the splendor of the rakiya;" and there also, it is a poetic expression. And so [likewise], in Malachi 3:10, "I will open for you the windows of the heavens," is by way of poetic expression. And we have also found a variant of rakiya referring to the heavens in Job 37:18, "Tarkiya (Did you spread out) the skies with Him;" and this too is a sign of the antiquity of this book. And he finishes [this verse], "they are as strong as a molten mirror," as they carry the weight of many waters. And so [too] did Shlomo say (Proverbs 8:28), "And in His strengthening of the skies above." And behold, the Torah spoke as in the language of people, and stated, "let there be a firmament," according to their thought (that it actually existed). And nonetheless, what was intended does not deviate from being true and solid, and that is that God implanted in the nature of water to rise upwards and to descend afterwards down to the earth. And in the Greek translation attributed to the seventy elders (the Septuagint), rakiya is translated as strauma, [which] is a matter of strength, and so [too] did they translate it afterwords into Latin [as] firmāmenta and this came to them from the use of the root, raka, in Syriac, which denotes strength; and so [too], rakiya in Syriac is strong and hard. And Johannes Clericus says that they translated it thus, because it was the opinion of some of the ancient philosophers that the heavens and air that surround the earth on all sides, prevent it and everything on it from getting detached and crumbling apart; and behold, they cause the earth to stay hard and its parts to remain fastened together. And he explains the expression to be one of hitting and trampling, as in "hit with your hand and stamp (reka) with your foot" (Ezekiel 6:11); "because you hit with your hand and you stamped (rakacha) with your foot" (Ezekiel 25:6); because the heavens are stamping on the earth and stopping its parts from detaching. And all of this is far from the simple meaning of the verses. And nonetheless, [his] words, that the origin of the root, raka, is from stomping and hitting, are plausible. And because something that is hit [becomes] flat and stretched out, the root, raka, is borrowed to indicate stretching out and flatness.

נשיאים. Bei Ismael und Israel heißen die Fürsten: נשיאים, bei Edom: אלופים .נשיאים heißen sonst Wolken, und der reinste Begriff des Fürsten ist damit gegeben. Was die Wolke ist, das hat sie von der Erde, und alles, was sie von der Erde empfängt, empfängt sie, um es, in Segen verwandelt, der Erde wieder zu spenden. Das ist der jüdische Fürst, den Kohelet 2, 12 als den bezeichnet, את אשר כבר עשוהו, den das Volk gemacht, d. i. der aus einer Vereinigung des Edelsten und Besten aus dem Volke bereits hervorgegangen ist. Es ist ein Glück, wenn der Fürst eine Wolke, ein נשיא ist. Ein solcher נשיא-Sinn ist notwendig, ohne ihn kann keine Gesamtheit blühen, und durch ihn werden die Gesamtkräfte des Volkes auf ein Ziel geleitet, dieses Ziel ist aber beim נשיא nicht die Wohlfahrt des Fürsten, sondern die Wohlfahrt des Volkes. Wie bei der Wolke der Erde, kommt durch den rechten Fürsten alle auf ihn vom Volke übertragene Macht und Fülle segnend dem Volke wieder zurück.
