Midrash su Esodo 26:28

Our masters have said (concerning Exod. 26:28): THE CENTER BAR < THROUGH THE MIDDLE OF THE BOARDS > came down to Egypt at the hands of Jacob, the one which served <as a bolt> FROM END TO END.⁴²On the miraculous bending of the bar around three sides of the Tabernacle, see Rashi and the Tosafot on Shab. 94b. It did not do so without the cedars uttering⁴³So also Yalqut Shim’oni, Exod. 369–370. Cf. Codex Vaticanus, Ebr. 34; Tanh., Exod. 7:9; etc., which read, “Not only that, but the cedars uttered….” a song, <i.e.> that which David utters (in I Chron. 16:33 // Ps. 96:12): THEN (az) SHALL ALL FOREST TREES SHOUT FOR JOY. THEN (az) is nothing but a song which one utters to the Holy One⁴⁴Tanh., Exod. 7:9 adds Exod. 15:1 as another example of this use of az. and says: When will the Tabernacle be made? Now when the Holy One said [to Moses] that he should make the Tabernacle, what did he say to him (in Exod. 26:15)? AND YOU SHALL MAKE THE BOARDS INTO A TABERNACLE <OF ACACIA WOOD>,⁴⁵The traditional vocalization of the verse would be translated: AND YOU SHALL MAKE THE BOARDS FOR THE TABERNACLE OF ACACIA WOOD; but the midrash assumes that the boards were already prepared. Cf. Tanh., Exod. 7:9, which inserts the following clarification here: “And you shall make boards” is not stated here, but AND YOU SHALL MAKE THE BOARDS. the same boards which their father (Jacob) had prepared for them. R. Samuel bar Nahmani said: There were twenty-four kinds of cedar; but from all of them, only seven were chosen.⁴⁶yKet. 7:11 (31d). Thus it is stated (in Is. 41:19): IN THE WILDERNESS I WILL PLANT THE CEDAR, THE ACACIA, THE MYRTLE, AND THE OLIVE; IN THE DESERT I WILL SET THE CYPRESS, THE PLANE TREE, AND THE ELM TOGETHER. Cypress is silver fir;⁴⁷Gk.: elate, i.e., pinus picea. plane is maple;⁴⁸Gk.: sphendamnos, i.e., acer. elm is boxwood,⁴⁹Gk.: pyxinon or pyxos, i.e., buxos. which is more approved than all species of cedar. But of them all, none was selected except the acacia alone. [It is so stated] (in Exod. 26:15): <AND YOU SHALL MAKE THE BOARDS FOR THE TABERNACLE> OF ACACIA (shittim) WOOD. And why did he call it shittim? Simply in order to heal what Israel did in Shittim (Numb. 25:1–9). Another interpretation (of Exod. 26:15): ACACIA (shittim) WOOD. They sinned in Shittim, and they were stricken in Shittim. They sinned in Shittim (according to Numb. 25:1): WHILE ISRAEL WAS STAYING AT SHITTIM, <THE PEOPLE BEGAN TO GO WHORING WITH THE DAUGHTERS OF MOAB>. And they were stricken in shittim (according to Numb. 25:9): AND THOSE WHO DIED FROM THE PLAGUE WERE <TWENTY-FOUR THOUSAND >. Moreover, they did not move from there until they were healed. Phinehas arose and turned back the wrath from them, as stated (in vs. 11): PHINEHAS BEN ELEAZAR <BEN AARON THE PRIEST HAS TURNED AROUND MY WRATH FROM UPON THE CHILDREN OF ISRAEL >…. The Holy One said: In the world to come I will heal the shittim, as stated (in Joel 4:18 [3:18]): AND IT SHALL COME TO PASS ON THAT DAY THE MOUNTAINS SHALL FLOW WITH FRESH GRAPE JUICE, THE HILLS SHALL RUN WITH MILK, AND [ALL] THE WATERCOURSES OF JUDAH SHALL RUN WITH WATER. THEN A SPRING SHALL ISSUE FROM THE HOUSE OF THE LORD AND SHALL WATER THE WADI OF THE ACACIAS (shittim).

“While the king was at his feast, my nard released its fragrance” (Song of Songs 1:12).
“While the king was at his feast,” Rabbi Meir and Rabbi Yehuda, Rabbi Meir says: While the King of kings was at His feast, in the firmament, Israel released a foul odor and said to the calf: “This is your god, Israel” (Exodus 32:4). Rabbi Yehuda said to him: ‘Enough, Meir, one does not expound Song of Songs disparagingly, but rather, favorably, as Song of Songs was given only in praise of Israel. What is: “While the king was at his feast”? While the King of kings was at His feast, in the firmament, Israel released a fine fragrance before Mount Sinai, and said: “Everything that the Lord has spoken we will perform and we will obey” (Exodus 24:7).
According to the opinion of Rabbi Meir, it should have said: My stench released its odor.²⁶⁸Since the verse was referring to the Golden Calf, it should have referred to stench rather than the fragrance of the sweet-smelling nard. Rather, a treatise ascended in their hand from the Diaspora,²⁶⁹The midrash is citing an ancient tradition recorded in a treatise that was transported from Babylon during the Return to Zion to build the second Temple. and they taught in its regard that He skipped the incident of the calf for them and the act of the Tabernacle preceded it.²⁷⁰The sin of the Golden Calf (Exodus chap. 32) should have been recorded in the Torah immediately following the events of the revelation at Sinai. Instead, it is preceded by the commandments concerning the building of the Tabernacle (Exodus chapters 25–31), to indicate that even when Israel sinned, they were still beloved in the eyes of the God. Therefore, the verse characterizes their odor as nard.
Rabbi Eliezer, Rabbi Akiva, and Rabbi Berekhya, Rabbi Eliezer says: “While the king was at his feast,” while the King of kings was at His feast, in the firmament, Mount Sinai was already enveloped in flames, as it is stated: “The mountain was burning with fire” (Deuteronomy 4:11). Rabbi Akiva says: While the King of kings was at His feast, in the firmament, already, “the glory of the Lord rested on Mount Sinai” (Exodus 24:16). Rabbi Berekhya says: While Moses was at his feast in the firmament,²⁷¹While he was still on Mount Sinai. as he is called king, as it is stated: “He became king in Yeshurun, when the heads of the people were assembled” (Deuteronomy 33:5), already, “God spoke all these matters saying” (Exodus 20:1).
Rabbi Eliezer ben Yaakov and the Rabbis, Rabbi Eliezer says: While the King of kings was at His feast, in the firmament, Mikhael, the great prince, had already descended from the heavens and rescued Abraham our patriarch from the fiery furnace. The Rabbis say: The Holy One blessed be He descended and rescued him, as it is stated: “I am the Lord who took you out of Ur of the Chaldeans” (Genesis 15:7). When did Mikhael descend? It was in the days of Ḥanaya, Mishael, and Azarya.²⁷²Mikhael is identified as the angel who descended to rescue Ḥananya, Mishael, and Azarya from the fiery furnace (see Daniel 3:25).
Rabbi Tavyomei said: While Jacob our patriarch was lying [mesev] in his bed, ²⁷³The expression “at his feast [bimsibo]” in the verse is interpreted as a reference to Jacob lying on his deathbed. the Divine Spirit gleamed in him, and he said to his sons: “God will be with you” (Genesis 48:21). He said to them: ‘He is destined to rest His Divine Presence in your midst.’ Rav Naḥman said: It is written: “Israel and everything that he had traveled and came to Beersheba” (Genesis 46:1). Where did he go? He went to chop down the cedars that Abraham our patriarch had planted in Beersheba, as it is stated: “He planted a tamarisk in Beersheba” (Genesis 21:33).²⁷⁴Jacob chopped them down in order to take them to Egypt. Rabbi Levi said: It is written: “The central bar inside the planks extending from end to end” (Exodus 26:28). The bar was thirty-two cubits long. From where did they have it in their possession at that moment?²⁷⁵Where did they get such a long piece of wood in the wilderness, just when they needed it to build this part of the Tabernacle? It teaches that they were hidden with them from the days of Jacob our patriarch. That is what is written: “And everyone with whom acacia wood was found” (Exodus 35:24); “acacia wood was found,” is not written here, but rather, “with whom…it was found”—from the outset.
Rabbi Levi bar Ḥiyya said: They chopped them down in Magdala of the dyers²⁷⁶This was the name of a place in the Land of Israel. and took them with them down to Egypt. They had no knots and no cracks. There were acacia trees in Magdala and the custom was to prohibit [using] them due to the sanctity of the Ark.²⁷⁷Even in the times of the Sages of the midrash, acacia trees grew in Magdala, but due to the tradition that the wood eventually used for the Ark and the rest of the Tabernacle had been cut from there, the people of Magdala would not make use of the acacia trees. They came and asked Rav Ḥananya, colleague of the Rabbis, and he said to them: Do not deviate from the custom of your ancestors.

14 "A brother offended is more formidable than a stronghold; such strife is like the bars of a fortress" (Proverbs 18:19). This is Korach, who violated the Torah - which is strength, as it is stated (Psalms 29:11), "May the Lord to His people give strength, may the Lord bless His people with peace." "Such strife is like the bars of a fortress" - and did he not know that his opponents were hard? "Like the bars of a fortress" - this is [referring to] Moshe and Aharon. Just like a bar does not move, so [too] Moshe, as it is stated (Exodus 26:28), "The center bar halfway up the planks shall run from end to end."
