Midrash su Salmi 91:10

… 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)

(Gen. 5:1:) THIS IS THE BOOK OF THE GENERATIONS OF ADAM. Let our master instruct us: May one cease being fruitful and multiplying at a time when he has no children? Thus have our masters taught (in Yev. 6:6): ONE IS NOT TO CEASE FROM BEING FRUITFUL AND MULTIPLYING UNLESS HE ALREADY HAS CHILDREN. THE BET SHAMMAY SAY: TWO MALES; BUT THE BET HILLEL SAY: A MALE AND A FEMALE, AS STATED (in Gen 5:2): MALE AND FEMALE HE CREATED THEM.⁸⁰Cf. Yev. 61b for a different explanation. What is the reasoning of the Bet Shammay? Through analogy with Cain and Abel.⁸¹I.e., after the birth of these two, there were no more children until Adam begot Seth after a long interval. See Gen. 5:3. What is the reasoning of the Bet Hillel? Through analogy with Adam and Eve. R. Simon said: Adam separated himself from his wife Eve for a hundred and thirty years after Abel was killed. Adam said: How am I to beget children when they go to destruction? What did he do? R. Simon said: Female spirits would come to him and become inflamed with passion from him; for so the Holy One told David (in I Chron. 22:8): BEHOLD, A SON SHALL BE BORN TO YOU, {AND} HE SHALL BE A MAN OF REST. (II Sam. 7:14:) I WILL BE TO HIM A FATHER, AND HE SHALL BE TO ME A SON. When? When he is busy in the Torah. But when he forsook me and walked in the way of his < own > heart, (ibid., cont.): WHEN HE TRANSGRESSES, I WILL PUNISH HIM WITH THE ROD OF MEN AND WITH THE PESTILENCES OF THE CHILDREN OF ADAM. What is the meaning of THE ROD OF MEN? These < words > refer to Hadad and Rezon ben Eliada. Thus it is stated (in I Kings 11:23) AND [GOD] RAISED UP AN ADVERSARY (satan) FOR HIM {FOR SOLOMON}, [REZON BEN ELIADA].⁸²The previous verses (14-22) concern the adversary. Hadad the Edomite. [AND WITH THE PESTILENCES OF THE CHILDREN OF ADAM.]⁸³Cf. Gen. R. 20:11; 24:6. PESTILENCES can only be the demons (mazziqin). Thus it is stated (in Ps. 91:10): NEITHER SHALL PESTILENCE COME NEAR YOUR TENT. < The above is > to make known to you that during the whole 130 years in which Adam had withdrawn from Eve, the spirits were coming to him and being inflamed with passion from him so that he was begetting demons (mazziqin).⁸⁴See ‘Eruv. 18b. At that time the Holy One said: I created my world only for fruitfulness and multiplying. So it is stated (in Is. 45:18): HE DID NOT CREATE IT AS A VOID; HE FORMED IT FOR HABITATION. What did the Holy One do? He put a sexual desire for Eve into the heart of Adam. So he had intercourse with her, and she bore Seth. Thus it is stated (in Gen. 5:3): WHEN ADAM HAD LIVED A HUNDRED AND THIRTY YEARS, HE BEGOT < A SON > IN HIS OWN LIKENESS {IN} [AFTER] HIS IMAGE. When Seth was born, Adam said: I did not ascribe my former sons a lineage. Why? Because they were accursed. But to this one I am ascribing a lineage because he is the head of [the] generations. Where is it shown? From what they have read on the matter (in Gen. 5:1-3): THIS IS THE BOOK OF THE GENERATIONS OF ADAM…. HE BEGOT < A SON > … AND CALLED HIS NAME SETH.
