One passage in Zohar says:
"the question is: not all mankind comes from Adam?
The truth is that Adam [human] is only found in the highest earth called: Tevel [תבל], and is linked to the higher firmament and the supreme name. Hence human is superior to all other creatures.
For, as there is a extremely high firmament high above that is the Throne of the Holy One, Blesses is He, so the king of everything is in this Tevel, that is, the human... ...In the book of the Sage Rav Hamnuna it is said tha the whole world is orbed like a balloon, so that some [people] are above, some are below, and the strange appearance of certain races are due to the nature of the air.. ..There is also a part of the World where there is light when the opposite part is dark, so that some have night while others have day.. ..Confirmed by the Scripture that says: 'I will give thanks to You, for I am fearfully and wonderfully made; wonderful are Your works; and that my soul knoweth right well' [Psal 139:14], and again: 'O Adonai, how manifold are your works!' [Psal 104:24].
This mistery that there are seven earths wrapping each other, was entrusted to the teachers of wisdom, the Kabbalists"
Zohar, Vayikra, page 10.
In this passage, what i see is the mention of seven earths wrapping each other, and those are called: the whole world, and mankind exists only in haTevel. And all of this information is compared to the firmament, as if the firmament also has layers.
Originally it is said: 'Elohim created heaven and the earth' (Gn 1:1), as if there's only one heaven.
But then I rememeber the words of Nehemiah: "You have made heaven [haShamayim], the heaven of heavens [shemei haShamayim], with all their host" [Neh 9:6]
and the words of Solomoh: "behold, heaven and the heaven of heavens cannot contain You" [1K 8:27].
As is stated in Torah: "unto HaShem your Elohim belongs the heaven, and the heaven of heavens, also the earth" [Dt 10:14]
Talmud Hagigah 12b teaches from here: there's 2 firmaments: (1) heavens and (2) the heaven of heavens.
Maimonides taught that the Sages counted the firmaments (in plural) as one. He said one heaven has 9 layers [referring the planets of the milky way], because all of them can be seen as if they were in the same sphere [the Earth]. Based on Dt 4:19 that says:
'you lift up your eyes to the heaven, and see the sun and the moon and the stars; all the hosts of heaven'.
Zohar says again: "God created seven heavens above and seven earths below, seven oceans, seven rivers, seven days, seven weeks, seven years, seven and sevenfold, and the seven thousands of the Earth".
Does the writer believe in a literal seven heavens or is a metaphorical concept? The answer is in the same verse. The verse says: God created seven years. I'm sure the writter lived more than that when he wrote the book. So he's trying to explain something deeper than a physical seventh Heaven. Is something spiritual, the layers of perfection. God made everything perfect. We see only one layer and we see things imperfect, but God sees the whole picture. In God eyes, the creation is perfect. That's what the Zohar meant.
The Psalm says: 'HaShem has established His throne in the heavens; and His kingdom rules over all.. ..Praise HaShem, all of His hosts.. ..everywhere in His dominion' [Psal 103:19-22]
So that's the extremly high firmament high above mentioned by the Zohar, the so called Throne of God.
When we read then the "third heaven" mentioned by Paul, we should understand some principles:
1- God dwells in the light which no man can approach unto [1Ti 6:16].
2- Paul calls that place: paradise (i.e gan Edén) [2Co 12:4].
3- Paul had a vision, he experimented a mystical trance, he had a revelation [2Co 12:1]
As is stated in Torah: 'if there be a prophet among you, I HaShem do reveal to him in a vision, I do speak with him in dreams'. [Nm 12:6]
So, depending of your Torah knowledge, you'll find more or less [spiritual] layers in the Heavens and in the Earth, but at the end, there's only one Heaven, and one Earth [Gn 1:1].
Shalom
