Midrasz do Wyjścia 29:46

… 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)

... You find [that] from the beginning of the creation of the world the Shekhinah rested/shartah among the lower ones...

"And it was on the day that Moses had finished" (Numbers 7:1). Rabbi Yehoshua ben Levi said, "The Holy One, blessed be He, made conditions with Israel before they left Egypt, that He would not take them out, except on condition that they make a tabernacle and that He would have His Divine Presence dwell upon them, as it is written (Exodus 29:46), 'And they shall know that I am the Lord, your God, who took you out of the Land of Egypt, to have Me dwell among you.'" And once the tabernacle was erected, the Divine Presence descended and dwelt among them. At that time all of those conditions were fulfilled. Hence it is written (Numbers 7:1), "the tabernacle," to [indicate] that the Holy One, blessed be He, did what He stipulated.
