Midrash su Salmi 68:8

R. Acha, the Galilean, said to R. Nachman b. Isaac: "There is no smiling by the Holy One, praised be He! since the Temple was destroyed, as it reads (Ib. 42, 14) I have long time held My peace, I have been still and refrained Myself. But what does He do in the last three hours? He teaches the Torah to the school-children. As it reads (Ib. 28, 9) Whom shall one teach knowledge? And whom shall one make to understand the message. Them that are weaned from the milk, them that are drawn from the breasts. And what does He do in the night-time? If you wish, it may be said that He does the same as in the day-time. And if you wish, it may be said that He rides upon His light cloud and moves in all directions upon eighteen thousand worlds. As it is said (Ps. 68, 8) The chariots of God are two myriads; thousands of angels (follow Him). And if you wish, it may be said that He sits and listens to the song of the angels, as (Ib. 42, 9) And in the night his song shall be with Me. R. Juda said in the name of Samuel: "What is the meaning of the passage (Hab. 1, 14) And makest men as the fish of the sea, as the creeping things, that have no ruler over them? Why are men compared to fish of the sea? To teach you that just as fish die as soon as they are taken on land, so do men die, when they separate themselves from the law and the commandments." Another explanation may be given to it: Just as fish die as soon as the heat of the sun penetrates to them, so also do men. If you wish it may be referred to this world, and this would be in accordance with R. Chanina, who said: "Everything is decreed by heaven, except cold, for the passage says (Pr. 22, 5), Thorns and snares are in the way of the forward; he that keepeth his soul holdeth himself far from them." And if you wish it may be referred to the world to come, and this is in accordance with Resh Lakish, who said: "There is no Gehenna in the future world, but the Holy One, praised be He! will bring forth the sun from its sheath with which the wicked will be punished and the upright cured." The wicked will be punished (Fol. 4), as it is written (Mal. 3, 19) For, behold, the day cometh, it burneth as a furnace; and all the proud and all that work wickedness, shall be stubble; and the day that cometh shall set them ablaze, saith the Lord of Hosts, that it shall leave them neither root nor branch. And the righteous will be cured thereby, as it is said, But unto you that fear My name shall the sun of righteousness arise with healing in its wings. Furthermore, the latter will have pleasure and become fat from it, as the passage says (Ib.) And ye shall go forth, and gambol as calves of the stall. There is another explanation [why men are likened unto fish]: Just as the larger fish in the sea, swallow the smaller, so also is it with man; if not for the fear of government the stronger would have swallowed the weaker. And this is meant by what we are taught in a Mishna that R. Chanina, the Vice-High-Priest, said: "Pray for the welfare of the government, since but for the fear thereof, men would swallow each other alive."

“Your neck is like the tower of David, built magnificently. One thousand bucklers are hung upon it, all the shields of the mighty” (Song of Songs 4:4).
“Your neck is like the tower of [kemigdal] David” – regarding which David elevated [gidel] you in his book. Regarding what did David elevate you in his book? “Who split the Red Sea asunder, [His mercy endures forever. He led Israel through its midst]” (Psalms 136:13).¹⁴The fact that Israel was the recipient of this great miracle is a credit to them. “Built magnificently [letalpiyot]” – what is letalpiyot? It is the book that was stated by many mouths [piyot]. Ten people said the book of Psalms: Adam the first man, Abraham, Moses, David, Solomon. Regarding these five there is no dispute. Who are the other five? Rav and Rabbi Yoḥanan: Rav said: Asaf, Heiman, Yedutun, the three sons of Koraḥ,¹⁵The three sons of Koraḥ are counted as one. and Ezra; Rabbi Yoḥanan said: Asaf, Heiman, and Yedutun are one,¹⁶Asaf is one of the sons of Koraḥ, and Yedutun is not the name of an author, as explained below. each of the three sons of Koraḥ, and Ezra. In the opinion of Rav, Asaf is not included among the sons of Koraḥ. In the opinion of Rabbi Yoḥanan, Asaf here is Asaf there;¹⁷The Asaf mentioned as an author of certain psalms (see, e.g., Psalms 50:1) is the same Asaf who was a son of Koraḥ (see Exodus 6:24, which mentions a son of Koraḥ named Aviasaf). however, because he was a Torah personality he was privileged to recite song with his brothers¹⁸The other sons of Koraḥ and to recite song on his own. In the opinion of Rav, it is a different Asaf, as it is stated: “With Asaf, who prophesied by means of the king” (I Chronicles 25:2).¹⁹The Asaf mentioned in this verse was a contemporary of King David and not a son of Koraḥ.
“Who prophesied” – Rav and Rabbi Yoḥanan: Rav said: “To Yedutun” (Psalms 39:1) – who prophesied;²⁰This psalm was written by the individual named Yedutun who is mentioned as having prophesied (See I Chronicles 25:1). “regarding Yedutun” (Psalms 77:1) – regarding the punishments [dinin] that befell him and Israel. Rabbi Yoḥanan said: “To Yedutun” [means] that [the psalmist] prophesied regarding the decrees [datin] and the punishment that befell him and Israel.²¹Even the Yedutun mentioned in Psalms 39 is not the name of a person. Rabbi Huna [said] in the name of Rabbi Aḥa: Even though ten people said the book of Psalms, of all of them, it is not attributed to them, but exclusively to David king of Israel. They stated a parable: to what is this matter analogous? It is to a group of people who seek to recite a hymn to the king. The king said: You are all pleasant, you are all pious, you are all qualified to recite a hymn before me. However, so-and-so will recite it on behalf of all of you. Why? Because his voice is sweet. So too, when ten righteous people sought to recite the book of Psalms, the Holy One blessed be He said to them: You are all pleasant, pious, and qualified to recite a hymn before Me; however, David will recite it on behalf of all of you. Why? Because his voice is sweet. That is what is written: “The sweet singer of Israel” (II Samuel 23:1). Rabbi Huna said in the name of Rabbi Aḥa: Who sweetly sings the psalms of Israel? It is David son of Yishai.
“One thousand bucklers are hung upon it” – all those thousands and tens of thousands who stood at the sea and I defended them. I defended them only because of the merit of what came after one thousand generations.²²The Torah was given after one thousand generations (see Bereshit Rabba 28:4; Kohelet Rabba 7:28). The first nine hundred seventy-four generations that were supposed to exist were erased because they were not worthy, and there were twenty-six generations from Adam to Moses.
“All the shields of the mighty” – to include one who stands and controls his inclination and overcomes his inclination, like Moses in his time, David in his time, Ezra in his time; his entire generation depends upon him. By means of whom was the Red Sea split for you? It was by means of “your two breasts” (Song of Songs 4:5) – these are Moses and Aaron.
Rabbi Yoḥanan interpreted the verse regarding Israel before Mount Sinai: the flock that stood at Mount Sinai did not stand with lightheartedness. “Behind your braid [tzamatekh]” (Song of Songs 4:3) – they would contract [metzamtzemin] themselves with each and every divine statement.²³They would huddle together in an expression of humility and unity. They would not stand with lightheartedness, but rather with fear, trembling, and agitation. Rabbi Abba bar Kahana in the name of Rabbi Yoḥanan cites it from here:²⁴This statement should appear after Rabbi Yehoshua’s statement that Israel was absolved of its sins at Sinai, which implies that the nations of the world, who did not receive the Torah, were still held accountable for their sins (Maharzu). It is written: “And the nations will be destroyed [ḥarov yeḥeravu]” (Isaiah 60:12) – from Ḥorev they will be destroyed, they received their death sentence.
“Your hair is like a flock of goats [that streams down [shegaleshu] from Mount Gilad]” (Song of Songs 4:1) – Rabbi Yehoshua said in the name of Rabbi Levi: The mountain from whose midst you took away [shegelashtem], I rendered it a memorial for the nations of the world. Which is this? This is Mount Sinai. What is it that you took away from its midst? “Your teeth are like a flock of ordered ewes” (Song of Songs 4:2) – defined matters, two hundred and forty-eight positive commandments and three hundred and sixty-five negative commandments. “That have come up from bathing” (Song of Songs 4:2) – all of them were cleansed of iniquity. Rabbi Aḥa and Rabbi Mesharshiya say in the name of Rabbi Idi: In all the additional offerings it is written: “And one goat as a sin offering” (Numbers 28:15), “and [one] goat as a sin offering” (Numbers 28:22). However, regarding Shavuot it is not written that there is a sin offering, to teach you that they did not have sin or iniquity attributed to them.
“That are all paired” (Song of Songs 4:2) – Rabbi Yoḥanan said: On the day that the Lord descended onto Mount Sinai to give the Torah to Israel, six hundred thousand ministering angels descended with him, and in the hand of each and every one of them was a crown with which to crown an Israelite, [one] for each and every one of Israel. Rabbi Abba bar Kahana [said] in the name of Rabbi Yoḥanan: One million two hundred thousand ministering angels descended with the Holy One blessed be He to Sinai; one would adorn [an Israelite] with a crown and one would gird a zoni on him. What is a zoni? Rabbi Huna the Great of Tzippori said: It is a belt [zonam], just as it says: “He loosens the bonds of kings and girds a belt on their waists” (Job 12:18). “And there is none missing among them” (Song of Songs 4:2) – that not one of them was harmed.
“Your lips are like a scarlet thread” (Song of Songs 4:3) – this is the voice before the divine speech; just as it says: “The entire people responded with one voice” (Exodus 24:3). “Your speech is lovely” (Song of Songs 4:3) – this is the voice that is after the divine speech, as it is stated: “The Lord heard the sound of your words…the Lord said to me: I heard the sound of the words…they did well in everything that they spoke” (Deuteronomy 5:25). What is “they did well [heitivu] in everything that they spoke”? Rabbi Ḥiyya bar Ada and bar Kappara: one said it was done well like the removal [hatava] of the ashes from the lamps of the candelabrum,²⁵This is performed after the flames are extinguished, a reference to what they said after the commandments. and one said it was done well like the preparation [hatava] of the incense.”²⁶This is performed before the incense is burned, a reference to what they said before the commandments. At that moment, Moses began lauding them: “Your temple [rakatekh] is like a pomegranate slice” (Song of Songs 4:3) – even the empty [hareikan] among you is packed with mitzvot like this pomegranate. It goes without saying: “Behind your braid [letzamatekh]” (Song of Songs 4:3) – regarding the modest and the fervent [metzumatin] among you.
“Your neck is like the tower of [kemigdal] David” – regarding which David elevated [gidel] you in his book. Regarding what did David elevate you in his book? “God, when You emerged before Your people” (Psalms 68:8). What is written thereafter? “The earth quaked…[this is Sinai; at the presence of God, the God of Israel]” (Psalms 68:9). Likewise, “The mountains flowed before the Lord; [this is Sinai before the Lord, God of Israel]” (Judges 5:5), as the verse did not need to say: “This is Sinai before the Lord, God of Israel.”²⁷It mentions Israel in order to accord them honor. “Built magnificently [letalpiyot]” – a book that was stated by many mouths [piyot].
“One thousand bucklers” – all those thousands and tens of thousands who stood before Mount Sinai and I defended them. I defended them only because of the merit of what came after one thousand generations.²⁸Moses You relied not only upon him, but rather, “all the shields of the mighty” – to include anyone who arises and controls and overcomes his inclination, like Moses in his time, David in his time, Ezra in his time. Their entire generations depend upon them. By means of whom was the Torah given? It was by means of “your two breasts” (Song of Songs 4:5) – these are Moses and Aaron.
