(6) There were five events that happened to our ancestors on the seventeenth of Tammuz and five on the ninth of Av.On the seventeenth of Tammuz: The tablets were shattered; The tamid (daily) offering was cancelled; The [walls] of the city were breached; And Apostomos burned the Torah, and placed an idol in the Temple. On the ninth of Av It was decreed that our ancestors should not enter the land, The Temple was destroyed the first And the second time, Betar was captured, And the city was plowed up. When Av enters, they limit their rejoicing.

(7) During the week in which the ninth of Av falls it is forbidden to cut the hair and to wash clothes but on Thursday it is permitted in honor of Shabbat. On the eve of the ninth of Av one should not eat a meal of two cooked dishes, nor should he eat meat or drink wine. Rabban Shimon ben Gamaliel says: one should make change [his diet.] Rabbi Judah obligated turning over the bed, but the sages did not agree with him.

(8) Section one: Rabbi Shimon ben Gamaliel said: There were no days of joy in Israel greater than the fifteenth of Av and Yom Kippur. Section two: On these days the daughters of Jerusalem would go out in borrowed white garments in order not to shame any one who had none. All these garments required immersion. The daughters of Jerusalem come out and dance in the vineyards. What would they say? Young man, lift up your eyes and see what you choose for yourself. Do not set your eyes on beauty but set your eyes on the family. “Grace is deceitful, and beauty is vain, but a woman that fears the Lord, she shall be praised” (Proverbs 31:30). And it further says, “Give her of the fruit of her hands; and let her works praise her in the gates” (ibid, 31:31). Section three: Similarly it says, “O maidens of Zion, go forth and gaze upon King Solomon wearing the crown that his mother gave him on his wedding day, on the day of the gladness of his heart” (Song of Songs 3:11). “On his wedding day”: this refers to Matan Torah (the Giving of the Torah). “And on the day of the gladness of his heart”: this refers to the building of the Temple; may it be rebuilt speedily in our days, Amen.

"Rising from the Grave"
Rabbi Jill Jacobs, in New York Jewish Week, July 24, 2012
from: Eichah Rabbah, Petichta 33
One of my favorite Midrashim imagines the Israelites’ response to learning that the entire generation that left Egypt would die in the wilderness, as the result of the report of the spies, a report delivered on Tisha b’Av. According to this Midrash, knowing their fate, each subsequent year the Israelites would dig their own graves before Tisha b’Av and then sleep in these graves on Tisha b’Av night. In the morning, they would get up and count who remained alive. And every time, they would find that 15,000 people (one-fortieth of the people who left Egypt) had died.
Finally, after 40 years had passed, the people again dug graves for Tisha B’Av, but in the morning everyone remained alive. Worried that they had gotten the date wrong, the people slept in their graves again the next night, and the next. Finally, after six nights had passed, they understood that their parents’ generation was entirely gone, and that everyone still alive would be allowed into the land. That day, according to Midrash, was Tu b’Av (15th of Av), which Jews still celebrate as a day of joy [Eicha Rabbah, Petichta 33].
That Tu b’Av morning, upon realizing that their parents’ reality was not their own, and they stepped out of the grave. They held on to the collective memory. And they moved on.
Eicha Rabba 1:51
The following story supports what Rabbi Yudan said in the name of Rabbi Aibu: A man was plowing his field when his ox lowed. An Arab passed by and asked "What are you?" And he answered "I am a Jew." The Arab man said to him, "Untie your ox and unharness your plough" [as a sign of mourning]. "Why?" he asked. "Because the Temple of the Jews is destroyed," said the Arab. "From where do you know that?" asked the Jew. "I know it because your ox lowed," answered the Arab. While they were talked the ox lowed again. "Harness your ox and tie up the plough again, because the deliverer (moshiach) of the Jews has been born" said the Arab. "What is his name?" asked the Jew. "Menachem (comforter)," answered the Arab.
....Rabbi Abun asks: Why do I need to be taught of this from the Arab man? I have the two pesukim 'And the Lebanon shall fall my a mighty one' which is closely followed by [and therefor connected to] 'And there shall come forth a shoot out of the stock of Jesse, and a twig shall grow forth from his roots.'

שוב פעם אחת היו עולין לירושלים כיון שהגיעו להר הצופים קרעו בגדיהם כיון שהגיעו להר הבית ראו שועל שיצא מבית קדשי הקדשים התחילו הן בוכין ור"ע מצחק אמרו לו מפני מה אתה מצחק אמר להם מפני מה אתם בוכים אמרו לו מקום שכתוב בו (במדבר א, נא) והזר הקרב יומת ועכשיו שועלים הלכו בו ולא נבכה אמר להן לכך אני מצחק דכתיב (ישעיהו ח, ב) ואעידה לי עדים נאמנים את אוריה הכהן ואת זכריה בן יברכיהו וכי מה ענין אוריה אצל זכריה אוריה במקדש ראשון וזכריה במקדש שני אלא תלה הכתוב נבואתו של זכריה בנבואתו של אוריה באוריה כתיב (מיכה ג, יב) לכן בגללכם ציון שדה תחרש [וגו'] בזכריה כתיב (זכריה ח, ד) עוד ישבו זקנים וזקנות ברחובות ירושלם עד שלא נתקיימה נבואתו של אוריה הייתי מתיירא שלא תתקיים נבואתו של זכריה עכשיו שנתקיימה נבואתו של אוריה בידוע שנבואתו של זכריה מתקיימת בלשון הזה אמרו לו עקיבא ניחמתנו עקיבא ניחמתנו:

The Gemara relates another incident involving those Sages. On another occasion they were ascending to Jerusalem after the destruction of the Temple. When they arrived at Mount Scopus and saw the site of the Temple, they rent their garments in mourning, in keeping with halakhic practice. When they arrived at the Temple Mount, they saw a fox that emerged from the site of the Holy of Holies. They began weeping, and Rabbi Akiva was laughing. They said to him: For what reason are you laughing? Rabbi Akiva said to them: For what reason are you weeping? They said to him: This is the place concerning which it is written: “And the non-priest who approaches shall die” (Numbers 1:51), and now foxes walk in it; and shall we not weep? Rabbi Akiva said to them: That is why I am laughing, as it is written, when God revealed the future to the prophet Isaiah: “And I will take to Me faithful witnesses to attest: Uriah the priest, and Zechariah the son of Jeberechiah” (Isaiah 8:2). Now what is the connection between Uriah and Zechariah? He clarifies the difficulty: Uriah prophesied during the First Temple period, and Zechariah prophesied during the Second Temple period, as he was among those who returned to Zion from Babylonia. Rather, the verse established that fulfillment of the prophecy of Zechariah is dependent on fulfillment of the prophecy of Uriah. In the prophecy of Uriah it is written: “Therefore, for your sake Zion shall be plowed as a field, and Jerusalem shall become rubble, and the Temple Mount as the high places of a forest” (Micah 3:12), where foxes are found. There is a rabbinic tradition that this was prophesied by Uriah. In the prophecy of Zechariah it is written: “There shall yet be elderly men and elderly women sitting in the streets of Jerusalem” (Zechariah 8:4). Until the prophecy of Uriah with regard to the destruction of the city was fulfilled I was afraid that the prophecy of Zechariah would not be fulfilled, as the two prophecies are linked. Now that the prophecy of Uriah was fulfilled, it is evident that the prophecy of Zechariah remains valid. The Gemara adds: The Sages said to him, employing this formulation: Akiva, you have comforted us; Akiva, you have comforted us.
The Shulchan Aruch (559:4) writes: We do not recite Tachanun on Tisha B'Av and we do not fall on our faces because it is considered a festival. Shulchan Aruch 559:4

(15) When Rabbi Meir died, the composers of fables ceased. When Ben Azzai died, the diligent students [of Torah] ceased. When Ben Zoma died, the expounders ceased. When Rabbi Joshua died, goodness ceased from the world. When Rabban Shimon ben Gamaliel died, locusts come and troubles multiplied. When Rabbi Elazar ben Azaryah died, the sages ceased to be wealthy. When Rabbi Akiba died, the glory of the Torah ceased. When Rabbi Hanina ben Dosa died, men of wondrous deeds ceased. When Rabbi Yose Katnuta died, the pious men (hasidim) ceased and why was his name called Katnuta? Because he was the youngest of the pious men. When Rabban Yohanan ben Zakkai died, the splendor of wisdom ceased. When Rabban Gamaliel the elder died, the glory of the torah ceased, and purity and separateness perished. When Rabbi Ishmael ben Fabi died, the splendor of the priesthood ceased. When Rabbi died, humility and fear of sin ceased. Rabbi Phineas ben Yair says: when Temple was destroyed, scholars and freemen were ashamed and covered their head, men of wondrous deeds were disregarded, and violent men and big talkers grew powerful. And nobody expounds, nobody seeks, and nobody asks. Upon whom shall we depend? Upon our father who is in heaven. Rabbi Eliezer the Great says: from the day the Temple was destroyed, the sages began to be like scribes, scribes like synagogue-attendants, synagogue-attendants like common people, and the common people became more and more debased. And nobody seeks. Upon whom shall we depend? Upon our father who is in heaven. In the footsteps of the messiah insolence (hutzpah) will increase and the cost of living will go up greatly; the vine will yield its fruit, but wine will be expensive; the government will turn to heresy, and there will be no one to rebuke; the meeting-place [of scholars] will be used for licentiousness; the Galilee will be destroyed, the Gablan will be desolated, and the dwellers on the frontier will go about [begging] from place to place without anyone to take pity on them; the wisdom of the learned will rot, fearers of sin will be despised, and the truth will be lacking; youths will put old men to shame, the old will stand up in the presence of the young, “For son spurns father, daughter rises up against mother, daughter-in-law against mother-in-law a man’s own household are his enemies” (Micah 7:6). The face of the generation will be like the face of a dog, a son will not feel ashamed before his father. Upon whom shall we depend? Upon our father who is in heaven. Rabbi Pinchas ben Yair says, “Heedfulness leads to cleanliness, cleanliness leads to purity, purity leads to separation, separation leads to holiness, holiness leads to modesty, modesty leads to fear of sin, fear of sin leads to piety, piety leads to the Holy Spirit, The Holy Spirit leads to the resurrection of the dead, and the resurrection of the dead comes from Elijah, blessed be his memory, Amen.”

"And they heard the sound of Hashem Elokim moving about in the garden in the windy part of the day." (Genesis, 3:8)... Rabbi Abba Bar Kahana said: It doesn't use the word מהלך here, but rather מתהלך, which implies jumping and rising. The Shechina was originally in the lower worlds, but when Adam sinned, it left to the first heaven. When Cain sinned, it left to the second, in the generation of Enosh to the third, in the generation of the flood to the fourth, in the generation of the tower of Babel to the fifth, in the generation of Sedom to the 6th, in the generation of the Egyptians to the 7th. 7 righteous men arose corresponding to them: Avraham, Yitzchak, Ya'akov, Levi, Kehos, Amram and Moshe. Avraham brought it down to the 6th, Yiztchak brought it down from the 6th to the 5th, Ya'akov brought it down to the 5th to the 4th, Levi brought it down from the 4th to the 3rd, Kehos brought it down from the 3rd to the 2nd, Amram brought it down from the 2nd to the 1st, and Moshe brought it down from above to below. Rabbi Yitzchak said: It is written "The righteous will inherit the land [and rest forever on it]." (Psalms, 37:29) Are the wicked floating in the air? Rather, [the intent of the verse is that] the wicked do not cause the Shechina to dwell on the land.
וְהַיְינוּ דְּאָמַר רַבִּי חִיָּיא בַּר אַמֵּי מִשְּׁמֵיהּ דְּעוּלָּא: מִיּוֹם שֶׁחָרַב בֵּית הַמִּקְדָּשׁ אֵין לוֹ לְהַקָּדוֹשׁ בָּרוּךְ הוּא בְּעוֹלָמוֹ אֶלָּא אַרְבַּע אַמּוֹת שֶׁל הֲלָכָה בִּלְבַד.
And this concept, that halakha is the most sublime pursuit, is expressed in that which Rabbi Ḥiyya bar Ami said in the name of Ulla: Since the day the Temple, where the Divine Presence rested in this world, was destroyed, the Holy One, Blessed be He, has only one place in His world where he reveals His presence exclusively; only the four cubits where the study of halakha is undertaken.
