מדרש אויף תהילים 89:52

R. Nachman said to R. Isaac: "Have you heard when the fallen son will come?" He was asked, "Who is the fallen son?" "Meshiah," answered R. Nachman. "And the Messiah, you call the fallen son?" And he answered: "Yes, for it is written (Amos 9, 11) On that day will I raise up (Fol. 97) the tabernacle of David, which is fallen." R. Isaac answered: "Thus said R. Jochanan: 'In the generation in which the son of David will come scholarly men will decerase, and the eyes of the remainder will protrude from sighing and sorrow; many chastisements and many evil decrees will be renewed; one will not have ceased, when another will have come'." Our Rabbis were taught: the Sabbatical period in which the son of David will appear there will be fulfilled in the first year the following passage (Am. 4, 7) And I caused it to rain upon one city, and upon another city I caused it not to rain. In the second year, slight famine will be sent. In the third, a great famine from which men, women and children, pious men and saints will die, and the Torah will be forgotten by the scholars. In the fourth, there will be partly abundance, and partly scarcity. In the fifth there will be great abundance, and the people will eat, drink, and enjoy themselves, and the Torah will return to her scholars. In the sixth, rumors will be heard saying that the Messiah is near. In the seventh, there will be war, and at the end of the seventh, ben David will come. "Were there not many Sabbatical periods," R. Joseph remarked, "which were like this, and still he did not come?" Abaye said: "Was it then as mentioned that rumors were heard in the sixth, and war in the seventh? And secondly, has it then happened in the same order as stated above?" It has been taught in a Baraitha that R. Juda said: "In the generation in which ben David will come, the school houses will be converted into debauchery. Galilee will be destroyed. The place called Gablan will be demolished. The Galileans will travel from one city to another, but will find no grace. The wisdom of the scribes will be corrupted. Men fearing sin will be hated. The leaders of that generation will have the nature of dogs. And the truth will be lacking as it is said (Is. 59, 15) And thus is the truth missing." What does the expression 'Ne'edereth mean? It was said in the college, they will form into various groups and disappear (Ib.) And he that departeth from evil is regarded as foolish. At the school of Shilah it was explained thus: "He who turns away from evil is regarded as foolish, in the eyes of the people."

Another matter: “My beloved spoke up, and he said to me” (Song of Songs 2:10). He answered me by means of Elijah and said to me by means of the messianic king. What did He say to me? Rise, my love, my fair one” (Song of Songs 2:10). Rabbi Azarya said: “For, behold, the winter [hasetav] is past” (Song of Songs 2:11), this is the kingdom of the Cutheans,¹¹³This is a reference to the Roman Empire. which incites [mesita] the entire world and misleads it with its lies, just as it says: “If your brother, son of your mother incites you […saying: Let us go and serve other gods]” (Deuteronomy 13:7). “The rain is over and gone” (Song of Songs 2:11), this is the subjugation. “The blossoms [hanitzanim] have appeared in the land” (Song of Songs 2:12), the administrators [hanatzoḥot] have appeared in the land. Who are they? Rabbi Berekhya [said] in the name of Rabbi Yitzḥak: It is written: “The Lord showed me four craftsmen” (Zechariah 2:3), these are: Elijah, the messianic king, Malki Tzedek, and the one anointed for war.¹¹⁴This term is generally used for the priest who would address soldiers before a battle (see Deuteronomy 20:2). However, in this context it presumably refers to Messiah ben Yosef, as stated explicitly in Sukka 52b (Maharzu).
“The time of the nightingale [zamir] has arrived” (Song of Songs 2:12), the time for Israel to be redeemed has arrived, the time for the foreskin to be cut off [shetizamer] has arrived, the time for the Cuthean kingdom to be eliminated has arrived, the time for the kingdom of Heaven to be revealed has arrived, as it is stated: “The Lord will be king over the entire earth” (Zechariah 14:9). “The sound of the turtledove [hator] is heard in our land” (Song of Songs 2:12), what is that? It is the voice of the messianic king who proclaims and says: “How pleasant are the footsteps of the herald on the mountains” (Isaiah 52:7).
“The fig tree has formed its unripe figs” (Song of Songs 2:13), Rabbi Ḥiyya bar Abba said: Just before the messianic era, a great pestilence will come to the world and the wicked will be eliminated. “The vines in blossom have emitted fragrance” (Song of Songs 2:13), these are those who remain, and in their regard it is written: “[Of] the remaining in Zion and the remnant in Jerusalem, [holy will be said]” (Isaiah 4:3).
Rabbi Yoḥanan said: The Sabbatical cycle during which the son of David comes, in the first year it will be fulfilled what is stated: “I will bring rain upon one city and will not bring rain upon another city” (Amos 4:7). During the second, arrows of famine will be shot.¹¹⁵This means that there will be a partial famine; there will be food shortages, but not full-fledged starvation (Rashi to Sanhedrin 97a). During the third there will be a great famine, and men, women, and children will die, and pious individuals and men of action will become few, and the Torah will be forgotten from Israel. During the fourth there will be famine but not famine, plenty but not plenty.¹¹⁶It will not be a great year of famine or plenty but something in between. During the fifth there will be great plenty and they will eat, drink, and rejoice, and the Torah will be renewed and restored to Israel. During the sixth, sounds [kolot];¹¹⁷This term, which can also be translated as voices or thunderings, can refer to great world events, rumors of the coming of Messiah, or the sounds of the shofar associated with the coming of the Messiah. during the Sabbatical Year, wars;¹¹⁸The war of Gog and Magog will be waged, involving the Jewish people. during the year after the conclusion of the Sabbatical Year, the son of David will come.
Abaye said: How many Sabbatical cycles like that have come, yet [the Messiah] did not come? Rather, it is as Reish Lakish said: In the generation in which the son of David will come, the assembly hall of the Sages will be for prostitution, the Galilee will be destroyed, the Gavlan¹¹⁹The Golan. will be desolate, and the residents of the Galilee will circulate from city to city and will receive no sympathy. The wisdom of scholars will be [considered] putrid,¹²⁰People will have no interest in or respect for their wisdom. those who fear sin and the people of kindness will be gathered,¹²¹They will pass away. truth will be lacking, and the face of the generation will be like the face of a dog.¹²²People will be brazen and have no inhibitions. From where is it derived that truth will be lacking? As it is stated: “Truth is lacking [nederet] and one who deviates from evil is deemed a fool” (Isaiah 59:15). Where does it go? The school of Rabbi Yanai says: It goes and sits in flocks [adarim] in the wilderness.¹²³Those who have the truth will be shunned and will gather in their own groups, apart from the rest of society.
The Rabbis say: In the generation in which the son of David will come, the Sages of the generation will die, the eyes of those who remain will fail due to sorrow and grief, many troubles and many evils will befall the public, and harsh decrees will be introduced and will be promulgated, [to the extent that] while the first one is extant another will come and be added to it.
Rabbi Nehorai said: In the generation in which the son of David will come, youths will humiliate elders and elders will stand before youths, “a daughter rises against her mother, and a daughter-in-law against her mother-in-law; a man’s enemies are the members of his household” (Micah 7:6), and a son will not be ashamed before his father. Rabbi Neḥemya says: Prior to the messianic era, poverty will proliferate, prices will be high, the vine will produce its fruit but the wine will spoil, and the entire monarchy will be transformed to heresy, but there will be no rebuke. Rabbi Abba bar Kahana said: The son of David will come only in a generation whose face is like that of a dog. Rabbi Levi said: The son of David will come only in a generation whose face is impudent and which is deserving of elimination. Rabbi Yanai said: If you see generation after generation reviling and blaspheming God, anticipate the footsteps of the messianic king. That is what is written: “For Your enemies revile the Lord; they revile the footsteps of Your anointed one” (Psalms 89:52). What is written thereafter? “Blessed be the Lord forever, amen and amen” (Psalms 89:53).

"What is the meaning of the verse 'I will sing to the Lord, for he is highly exalted'? Rabbi Yudan said that this refers to what is written in Psalms 71:7, 'I have become a sign to many; you are my strong refuge.' David said, 'I did not sing a song until I was disgraced and until four fell into my hand and until I had dominion over Baal of the fingers.' So too, Israel does not sing a song until they are disgraced and until four fall into their hands and Baal of the fingers. This is the meaning of 'I have become a sign to many, and you are my strong refuge.' How did David become disgraced? He revealed the Philistine's secrets (see 1 Samuel 17) and disgraced Israel, and cursed David, and he fell into his hand. And Baal of the fingers (see 2 Samuel 21:20) was a man from Judah with six fingers on each hand, and four of his descendants fell before David (see 2 Samuel 21:22). David spoke this song to the Lord (see 2 Samuel 22:1). Similarly, when the Messiah comes quickly in our days, we do not sing a song until the Messiah is disgraced, as it is written in Psalms 69:10, 'Because zeal for your house consumes me, and the insults of those who insult you fall on me.' And until four wicked empires fall before him, as it is written in Zechariah 14:2, 'I will gather all the nations to Jerusalem,' and then the Lord will go out and fight. At that time, one should say a new song to the Lord, as it is written in Psalms 98:1, 'Sing to the Lord a new song, for he has done marvelous things.'"
