Midrash su Esodo 40:34

… it is written there “Behold the heaven and the heaven of heavens cannot contain You…” (Melachim I 8:27) and here it is written “…the glory of the Lord filled the Tabernacle.” (Shemot 40:35) R’ Yehoshua of Sachnin said in the name of R’ Levi ‘to what is this likened? To an open cave at the edge of the sea. When the sea storms the cave is filled, but the sea is not reduced. So too, even though it is written that ‘the glory of the Lord filled the Tabernacle’ the upper and lower worlds did not lose anything of the brilliance of the glory of the Holy One, just as it is written “Do I not fill the heavens and the earth? says the Lord.” (Yirmiyahu 23:24) Therefore it is written here ‘And it was’. Just as the Divine Presence was here below at the beginning of the creation of the world but withdrew to above, now it returned to be below as it had been “And it was that on the day that Moses finished…” (Bamidbar 7:1) ... [Another explanation. “And it was that on the day that Moses finished erecting the Mishkan…” (Numbers 7:1)] R’ Simon said: at the time when the Holy One told Israel to erect the Tabernacle, He hinted that when the Tabernacle below is erected, the Tabernacle above is erected, as it says “And it was that on the day that Moses finished…” (ibid.) It does not say ‘erecting the Tabernacle’ but rather ‘erecting this (et) the Tabernacle.’ This refers to the Tabernacle above. The Holy One said: in this world, when the Tabernacle was erected, I commanded Aharon and his sons that they bless you. In the time to come I, in my glory, will bless you. So it is written “May the Lord bless you from Zion, He Who made heaven and earth.” (Psalms 134:3)

These are the accounts of the Tabernacle. It is written elsewhere: Now these are the names of the sons of Israel (Gen. 46:8). Observe how very precious the Tabernacle was to the Holy One, blessed be He, that He left the upper sphere to dwell in the Tabernacle. R. Simeon held that He dwelt in the lower sphere (at first), as is said: And they heard the voice of the Lord God walking in the garden (ibid. 3:8), but that after Adam sinned He ascended from earth to heaven. When Cain arose and killed his brother, He ascended from the first firmament to the second; when the generation of Enoch angered Him, He ascended from the second to the third; when the generation of the flood perverted His teaching, He ascended from the third to the fourth; when the generation of the separation (i.e., the Tower of Babel) became arrogant, He went from the fourth to the fifth sphere; when the Sodomites behaved immorally, He went from the fifth to the sixth; and when Amraphel and his companions appeared, He ascended from the sixth to the seventh. However, after Abraham came and performed good deeds, the Shekhinah descended from the seventh to the sixth firmament; after Isaac He went from the sixth to the fifth; after Jacob from the fifth to the fourth; after Levi, his son, from the fourth to the third; after Kohath the son of Levi, from the third to the second; after Amram from the second to the first; and on the day that Moses erected the Tabernacle: The glory of the Lord filled the Tabernacle (Exod. 40:34). Scripture states: For the upright shall dwell in the land (Prov. 2:21). This should be read: “They caused the Shekhinah to dwell in the land.”

Has it not already been stated: Do I not fill heaven and the earth (Jer. 23:24)? R. Joshua of Sikhnin said in the name of R. Levi: This may be compared to a cave situated at the edge of the sea. Though the sea rushes forth and fills the cave, the sea lacks nothing. Similarly with the Holy One, blessed be He, may His name be blessed, for though it is written: And the glory of the Lord filled the Tabernacle (Exod. 40:34), nevertheless His glory is above the heaven and the earth (Ps. 148:13). You should not say that the Holy One, blessed be He, compressed His Shekhinah only into the Tabernacle. He likewise compressed His Shekhinah into the ark that Bezalel had made, as it is written: Behold, the ark of the covenant of the Lord of all the earth (Josh. 3:11). This indicates that the Holy One, blessed be He, was within it. Who other than Bezalel could have made it, since it says: And Bezalel made the ark?
