Midrasch zu Schir haSchirim 8:6

R. Samuel b. Nachmeni, in the name of R. Jonathan, said: Three men made an unreasonable demand (making their actions dependent on chance); two of them were answered desirably (Providence favored their ways), but one was answered according [to his unreasonableness]. They are: Eliezer, the servant of Abraham; Saul, the son of Kish; and Jephthah, of Gilead. Concerning Eliezer it is written (Gen. 24, 13) … and the daughters of the men of this city come out to draw water, etc. Now, such a maiden might have been blind or maimed, nevertheless he was answered desirably when Rebekah came [providentially] to him. Concerning Saul, the son of Kish, it is written (I Sam. 17, 25) And it shall be, that the man who killeth him, the king enrich him with great riches, and will give him his daughter, etc. It might have happened that a slave, or an illegitimate son, might accomplish the feat, nevertheless he was answered desirably; and David came [providentially] to him. Concerning Jephthah it is written (Jud. 11, 31) Then it shall be, that whatsoever cometh forth of the doors of my house … I will offer it up for a burnt-offering. An unclean animal might have come forth [which would not be a proper sacrifice] . He was therefore answered undesirably, for his own daughter came [providentially] to meet him. This is meant by the words of the prophet (Jer. 8, 22) Is there no mere balm in Gilead? Or, is no physician there? And further, it is written (Ib. 19, 5) which I had not commanded nor spoken, and which had not come into my mind; i.e., which I had not commanded refers to the son of Mesha, the King of Moab, as it is said (II Kings, 3, 27) Then he took his eldest son that should have reigned in his stand, and offered him for a burnt-offering upon the wall. And there came great wrath upon Israel; and they departed from him, and returned to their own land; nor spoken, refers to the daughter of Jephthah, the Gilodite; and which had not come into my mind, refers to Isaac, son of Abraham." R. Berachia said: "The congregation of Israel also made an unreasonable demand, but the Holy One, praised be He! answered it in a desirable manner, as it is written (Hos 6, 3) And let us know, eagerly strive to know the Lord; His going forth is sure as the morning; and He shall come unto us as the rain, as the latter rain that watereth the earth. The Holy One, praised be He! said: 'My daughter, thou askest a thing which is sometimes desirous and sometimes superfluous, nevertheless I shall be to thee as a thing which is needed all the time; as it is said (Ib. 14, 6) I will be as the dew unto Israel. Another time did the congregation of Israel make an unreasonable demand, saying: 'Sovereign of the universe! (Songs 8, 6) Set me as a seal upon thy heart, as a seal upon thy arm.' Whereupon the Lord said: 'Thou askest me to do a thing which sometimes can be observed and sometimes cannot; but I will set thee as a seal in such a place that you will always be observed'; as it is said (Is. 49, 16) Behold, upon the palms of my hands have I engraved thee."

“Who is that ascending from the wilderness, leaning upon her beloved? Under the apple tree I roused you; there your mother was in travail with you; there she who bore you was in travail” (Song of Songs 8:5).
“Who is that ascending from the wilderness” – [Israel’s] ascent was from the wilderness, its decline was from the wilderness, and its death was from the wilderness. That is what it says: “In this wilderness they will expire, and there they will die” (Numbers 14:35). “Leaning [mitrapeket] upon her beloved” – Rabbi Yoḥanan said: Because it will resolve sections of the Torah and issues of kingdom in the future.⁵Mitrapeket when rearranged is a portmanteau of matir perek – resolves a section. In the future, Israel will resolve all questions relating to Torah, and will reestablish its monarchy. “Under the apple tree I roused you” – Pelatyon of Rome expounded and said: Mount Sinai was detached and positioned in the supernal heavens, and Israel was situated beneath it, as it is stated: “You approached and stood beneath the mountain” (Deuteronomy 4:11).
Another matter: “Under the apple tree I roused you” – this is Sinai. Why is it likened to an apple tree? Just as the apple tree produces fruit in the month of Sivan, so too, the Torah was given in Sivan. Alternatively, “under the apple tree I roused you” – why not a nut tree or a different tree? Each tree typically grows its leaves first and then its fruit, but the apple tree grows its fruit first and then grows its leaves. Similarly, Israel put performing before hearing, as it is stated: “We will perform and we will heed” (Exodus 24:7).⁶Although translated here as “heed,” the term nishma can be translated “hear.” The point here is that Israel committed to following God’s commands even before hearing what they were. The Holy One blessed be He said: ‘If you accept My Torah upon yourself, fine, but if not, I will lower this mountain upon you and kill you.’ “There your mother was in travail with you” – was it there that she was in travail? Rabbi Berekhya said: This is analogous to one who went to a dangerous place and was saved. His friend encountered him and said to him: ‘Did you pass through that dangerous place? How much danger you experienced! It is as though you were now borne by your mother. How much suffering you experienced! Now it is as though you were created as a new creation.’
Rabbi Abba bar Kahana said: “There [your mother] was in travail [ḥibela]” and there she had collateral taken from her [ḥubela]; “was in travail” – at the moment that they said: “Everything that the Lord spoke we will perform and we will heed” (Exodus 24:7). She had collateral taken from her – at the moment that they said to the calf: “This is your God, Israel” (Exodus 32:4), they had collateral taken. Rabbi Shimon ben Yoḥai taught: The weapon that was given to Israel at Ḥorev had the ineffable name etched upon it.⁷This is stated in explanation of the adornment mentioned in the verse: “The children of Israel were stripped of their adornment from Mount Ḥorev” (Exodus 33:6). When they sinned it was taken from them. Rabbi Aivu and the Rabbis: Rabbi Aivu said: It was peeled on its own. The Rabbis say: An angel descended and peeled it. Rabbi Shimon ben Ḥalafta said: Wretched is the bride who sins under the wedding canopy. Rabbi Yoḥanan said: They lost the good counsel that was given them at Sinai, as it is stated: “You hollowed all my counsel” (Proverbs 1:25), and counsel is nothing other than Torah, as it is stated: “Counsel and resourcefulness are mine” (Proverbs 8:14).
Rabbi Yehoshua of Sikhnin [said] in the name of Rabbi Levi: It is written: “At Ḥorev you provoked [hiktzaftem] the Lord” (Deuteronomy 9:8). The Holy One blessed be He said: I came to bless you and found your palate pierced and unable to hold a blessing, as it is stated: “Moses saw the people that it was parua (Exodus 32:25), and parua means nothing other than hollowed, just as you say: “You hollowed [vatifre’u] all my counsel” (Proverbs 1:25). Rabbi Levi said: You made the Holy One blessed be He as though He was mourning over you. There are places that call the house of mourning the house of wrath [beit ketzofa].

“Place me as a seal upon your heart, as a seal upon your arm, for love is as intense as death, jealousy is as cruel as the grave; its sparks are the sparks of fire, a great conflagration” (Song of Songs 8:6).
“Place me as a seal” – Rabbi Meir said: Israel said before the Holy One blessed be He: ‘Master of the universe, do what You thought in Your heart to do to us,’ as Rabbi Yoḥanan said in the name of Rabbi Eliezer, son of Rabbi Yosei HaGelili: When Israel stood before Mount Sinai and said: “We will perform and we will heed” (Exodus 24:7), at that moment the Holy One blessed be He called the Angel of Death and said to him: ‘Even though I appointed you chief executioner for the whole world, you are to have no involvement with this nation.’ That is what is written: “It was when you heard the voice from the midst of the darkness” (Deuteronomy 5:20). Is there darkness On High? But is it not written: “The light rests with Him” (Daniel 2:22)? What then is “from the midst of the darkness”? This is the Angel of Death, who is called darkness. And it is stated: “The tablets were the work of God and the script was the script of God, engraved [ḥarut] upon the tablets” (Exodus 32:16) – do not read it as engraved [ḥarut], but rather as freedom [ḥerut]. Rabbi Yehuda, Rabbi Neḥemya, and the Rabbis: Rabbi Yehuda said: Freedom from the Angel of Death. Rabbi Neḥemya said: Freedom from the [gentile] kingdoms. And the Rabbis say: Freedom from suffering.
