Midrash su Ecclesiaste 2:8

(Ecc. 2, 8) I procured men singers and women singers, and the delights of the sons of men, and Shidda and Shidath; i.e., men singers and women singers, refers to different musical instruments and the delight of the sons of men refers to swimming pools and bath houses. As to Shidda and Shiddath here (in Babylon) it was interpreted to signify male demons and female demons, while in the West (the land of Israel) they said it means carriages [for lords and ladies, respectively]. Said R. Jochanan: "Three hundred" different kinds of demons were to be found in Sichin [all of whom were known to me], nevertheless the kind called Shidda is unknown to me." The master said above: "Here (in Babylon) it was interpreted to signify male demons and female demons." For what purpose did King Solomon require them? The following passage will answer (I Kings 6, 7) And the house, when it was in building, was built of stone made ready before it was brought thither, etc. For before the operation [of the Temple] commenced Solomon asked the Rabbis: "How shall I accomplish this?" (without using tools of iron.) Whereupon they replied: "There is the Shamir, with which Moses cut the precious stones of the Ephod." "Where is it to be found?" Solomon asked the Rabbis. To which they replied, "Let a male demon, and a female come' and do thou coerce them both; perhaps they know and will reveal it to thee." He then conjured into his presence a male and a female demon, and tortured them. But in vain, for they said: "We do not know his whereabouts, and cannot tell; perhaps Ashmedai, the king of the demons, knows." "But where is he to be found?" Solomon inquired of them. They answered: "In yonder mount is his residence. There he has a pit and, after filling it with water, covered it over with a stone and sealed with his own seal. Daily he ascends to heaven and studies in the school up there; then he comes down and studies in the school down here. After this he goes and examines the seal, then opens the pit and after quenching his thirst covers it up again and seals it and departs."

It is taught: Until a person sins, he is given terror and fear and creatures are afraid of him. Once he sins, terror and fear are imposed upon him and he is afraid of others. Know that it is so, as Rabbi said: Until Adam the first man sinned, he would hear the voice of divine speech while standing on his feet and was not afraid. Once he sinned, when he heard the voice of divine speech, he was afraid and hid, as it is stated: “I heard your voice…” (Genesis 3:10); “the man hid” (Genesis 3:8). Rabbi Aivu said: At that moment the height of Adam’s stature diminished and it became only one hundred cubits. Rabbi Levi said: Until Adam the first man sinned, he would hear a soothing divine voice. Once he sinned, he would hear a thundering voice.
Until Israel sinned, they would see⁹⁰They would see the glory of God. through the consecutive partitions and they were not afraid, shocked, and frightened. Once they sinned, they could not have even looked at an intermediary. That is what is written: “They saw the skin of Moses’s face, that it was radiant” (Exodus 34:35), and it is written: “They feared to approach him” (Exodus 34:30).
Rabbi Pinḥas and Rabbi Avun said in the name of Rabbi Ḥanin: Even the intermediary was affected with them in that transgression. Until Israel sinned, what is written? “The kings of armies flee again and again” (Psalms 68:13). Rabbi Aivu said: “Angels [malakhei] of armies” is not written, but rather “kings [malkhei] of armies”—the kings of the angels. Which is they? They are Mikhael and Gavriel. They were unable to look at Moses’s face. Once [the Israelites] sinned, [Moses] was unable to look even at the most ordinary among [the angels]. That is what is written: “For I was in dread of the wrath and the fury” (Deuteronomy 9:19).
Until that incident befell David,⁹¹The reference is to David’s sin with Batsheva. See II Samuel chap. 11. it is written: “The Lord is my light and my salvation; whom shall I fear?” (Psalms 27:1). Once it befell him, it is written: “I will come upon him, and he will be weary and discouraged” (II Samuel 17:2). Until Solomon sinned, he would subjugate sharim and sharot.⁹²The meaning of these words is unclear. Perhaps it may be read sarim and sarot, in which case it means princes and princesses. Alternatively, some suggest that the text should read shedim veshedot, male and female demons. That is the text found in a parallel midrash in Yalkut Shimoni Tehillim 795. That is what is written: “I acquired for myself male and female singers [sharim vesharot]” (Ecclesiastes 2:8), male singers [meshorerim] and female singers [meshorerot];⁹³In this phrase, the midrash has merely translated the terms used in the verse to more familiar forms of the words. “and the pleasures of people” (Ecclesiastes 2:8), bathhouses; “chests [shida] and wagons [shidot]” (Ecclesiastes 2:8), male and female demons [sheda veshedta] who would heat them. Once he sinned, he appointed for him “sixty valiant men…from the valiant of Israel” and positioned them to protect his bed. That is what is written: “Behold the bed…each armed with a sword,” because he was afraid of the spirits.
