Midrash su Cantico dei cantici 4:5

“Your two breasts are like two fawns, twins of a gazelle, that graze among the lilies” (Song of Songs 4:5).
“Your two breasts” – these are Moses and Aaron. Just as the breasts are the splendor and the glory of a woman, so too, Moses and Aaron are the splendor and the glory of Israel. Just as the breasts are the beauty of the woman, so too, Moses and Aaron are the beauty of Israel. Just as the breasts are the honor and praise of a woman, so too, Moses and Aaron are the honor and the praise of Israel. Just as the breasts are filled with milk, so too, Moses and Aaron fill Israel with Torah. Just as the breasts, everything that the woman eats, the baby eats and suckles from them, so too, all the Torah that Moses our master studied, he taught to Aaron; that is what is written: “Moses told Aaron all the words of the Lord” (Exodus 4:28). The Rabbis say: He revealed to him the ineffable name. Just as the breasts, one of them is not larger than the other, so it was with Moses and Aaron. That is what is written: “That Moses and Aaron” (Exodus 6:27), and it is written: “That Aaron and Moses” (Exodus 6:26). Moses was not greater than Aaron, and Aaron was not greater than Moses in Torah.
Rabbi Abba said: [This is analogous] to a king who had two fine pearls, and he placed them on the pans of a balance scale; this one was not greater than that one and that one was not greater than this one. So too, Moses and Aaron were equal. Rabbi Ḥanina bar Pappa said: Blessed is the Omnipresent who selected these two brothers, who were created only for the Torah and for the glory of Israel. Rabbi Yehoshua of Sikhnin said in the name of Rabbi Levi: There were two families of priests in Alexandria; the body temperature of one was cold and [that] of the other one’s was hot. There was an incident where doctors sent for some of them and they prepared a suspension from them with which they would heal.⁷⁹They took tissue from bodies in each family, and the combination was just right and could be used as a healing ointment. So too, Moses and Aaron complemented each other in leading Israel.
Rava in the name of Rabbi Shimon: Flesh and blood does not prepare a dressing until he sees the wound; however, He who spoke and the world came into being is not so, but rather He prepares the dressing and then strikes. That is what is written: “Behold I am bringing it a remedy and a cure, and I will heal them…” (Jeremiah 33:6),⁸⁰He prepared the cure for Jerusalem before He struck it. and it is written: “When I will heal Israel” (Hosea 7:1). The Holy One blessed be He said: I came to heal the iniquities of Israel, “and the iniquity of Ephraim and the evils of Samaria will be revealed” (Hosea 7:1).⁸¹Only after preparing the cure will they be taken to task for their wickedness. However, the nations of the world, He strikes them and only then heals them, as it is stated: “The Lord will strike Egypt, striking and healing” (Isaiah 19:22). Striking by means of Aaron and healing by means of Moses. Blessed are these two brothers who were created only for the glory of Israel. That is what the prophet Samuel said: “The Lord who produced Moses and Aaron” (I Samuel 12:6). That is “your two breasts” – these are Moses and Aaron.

“Twins of a gazelle” – Rabbi Yehoshua of Sikhnin in the name of Rabbi Levi: Just as these twins, when one of them withdraws from the breast, the breast is blocked, so it is written: “I will eliminate the three shepherds in a single month” (Zechariah 11:8).⁸²This is a reference to Moses, Aaron, and Miriam. But is it not so that they died only within the same year?⁸³They died in one year, but not in the same month. Rather, in a single month, the decree was issued regarding the three of them. That is what is written: “The great ones of the people were gathered” (Psalms 47:10).
Rabbi Yosei says: Three great providers arose for Israel, and these are: Moses, Aaron, and Miriam. Through their merit, three great gifts were given to them: The well, the manna, and the clouds of glory. The manna, through the merit of Moses; the well through the merit of Miriam; and through the merit of Aaron, the clouds of glory. Miriam died and the well ceased, and they said: “Not a place of seed, fig [and pomegranate, and there is no water to drink]” (Numbers 20:5). But it was restored due to the merit of Moses and Aaron. Aaron died, and the clouds of glory disappeared. That is what is written: “The entire congregation saw [vayiru] that Aaron had perished” (Numbers 20:29). Do not read it as “they saw [vayiru],” but rather as “they feared” [vayire’u].”⁸⁴They were afraid because the protection of the clouds of glory had disappeared. They were restored through the merit of Moses. Moses died and all three of them disappeared and they were not restored. The hornet did not cross the Jordan with them⁸⁵God promised to send hornets to assist in expelling the Canaanite nations (see Exodus 23:28). However, in the absence of Moses they did not cross the Jordan and assisted with Israel’s battles only east of the Jordan. and Israel did not experience peace of mind from that time forward.
“That graze [haro’im] among the lilies” – Shmuel bar Naḥmani said: Miriam and Yokheved were the midwives of Israel, and they would provide for [ro’ot] Israel as their hearts were as soft as lilies. Where was the pasture of Israel? It was in Egypt until the Red Sea.⁸⁶It was there that Miriam and Yokheved tended to the needs of the birthing mothers and their offspring.

Moses was keeping the flock. Though the time for their redemption was at hand, they had not as yet performed any meritorious deeds. Scripture declares this through the words of Ezekiel: I caused thee in increase even as the growth of the field … thy breasts were fattened, and thy hair was grown, yet thou wast naked and bare (Ezek. 16:7). Is it not so that the Holy One, blessed be He, would not have written breasts and hair except for the fact that breasts and hair allude to Moses and Aaron? Inasmuch as it is said concerning them: Thy two breasts are like two fawns, that are twins of a gazelle (Song 4:5). Thy hair was grown implies that the time for redemption had arrived, but naked and bare signify that Israel had not yet performed any good deeds. The verse For thy love is better than wine (ibid. 1:2) refers to the patriarchs, who are called beloved. And God heard their groaning, and remembered His covenant with Abraham, with Isaac, and with Jacob. And God saw the children of Israel (Exod. 2:24). That is, though He saw that they had not yet performed any meritorious deeds, He redeemed them nevertheless, as is said: He saved them for His name’s sake (Ps. 106:8).

How were the Ten Commandments given? Five on one tablet and five on the other. "I am the L rd your G d," and opposite it "You shall not kill," whereby Scripture apprises us that spilling blood is tantamount to "diminishing" the likeness of the King. An analogy: A king of flesh and blood enters a province, sets up statues of himself, makes images of himself, and mints coins in his likeness. After some time, they upset his statues, break his images, devalue his coins — and "diminish" the likeness of the king. Likewise, Scripture equates spilling blood to "diminishing" the likeness of the King, as it is written (Genesis 9:6) "One who spills the blood of man … (For in the image of G d did He make man.") It is written "There shall not be unto you any other gods in My presence," and, opposite it, "You shall not commit adultery," whereby Scripture apprises us that idolatry is tantamount to adultery. As it is written (Ezekiel 16:32) "You are the (very essence of the) adulterous woman, who (though) living with her husband, (still) takes strangers," and (Hoshea 3:1) "And the L rd said again to me: "Go and love a woman beloved by her husband, and playing the harlot under him — just as the L rd loves the children of Israel, while they turn to other gods…" It is written "You shall not take the name of the L rd your G d in vain," and, opposite it, "You shall not steal," whereby we are apprised that one who steals, in the end comes to swear in vain, as it is written (Jeremiah 7:9) "Shall one steal, murder, commit adultery, swear falsely (… and go after the gods of others, etc.?" And it is written (Hoshea 4:2) "swearing, lying, murdering, stealing, (committing) adultery…" It is written "Remember the Sabbath day to sanctify it," and, opposite it, "You shall not testify (falsely)," whereby Scripture apprises us that one who desecrates the Sabbath thereby testifies before Him who spoke and brought the world into being that He did not create His world in six days and did not rest on the seventh day, and that one who keeps the Sabbath thereby testifies before Him who spoke and brought the world into being that He created His world in six days and rested on the seventh day, as it is written (Isaiah 43:10) "You are My witnesses, says the L rd … that I am He. Before Me no god was created and there will be none after Me." It is written "Honor your father and your mother," and, opposite it, "You shall not covet," whereby Scripture apprises us that whoever covets, in the end comes to beget a son who curses his father and honors one who is not his father. This is why the Ten Commandments were given, five on one tablet and five on the other. These are the words of R. Chanina b. Gamliel. The sages say: (They were given) ten on one tablet and ten on the other. As it is written (Devarim 5:19) "These things (the ten commandments) the L rd spoke … And He wrote them on two tablets of stone." And (Song of Songs 4:5) "Your two breasts are like two fawns, twins of a gazelle." And (Ibid. 5:14) ("The tablets of) His hands are wheels of gold, set with emeralds."...
