Midrash su Deuteronomio 32:36

R. Nehorai taught: "The generation in which the son of David will come, the young will expose the old to public shame, and the old will rise [in token of respect] before the young; a daughter will rebel against her mother, a daughter-in-law against her mother-in-law, the leaders of the generation will have the nature of dogs, and a son will not be ashamed when reproached by his father." We are taught in a Baraitha: R. Nehemiah says: "The generation in which ben David will come, insolence will increase, respect will be missing, the vine will give forth its fruit abundantly; nevertheless wine will be dear, and all the governments will be turned to the Minuth, and no admonition will avail." This is in accordance with R. Isaac, who said that ben David will not come unless all governments will be turned over to Minuth. Raba said: "Where is the passage for it?" (Lev. 13, 13) It is all turned white, he is clean. Our Rabbis were tought: (Deut. 32, 36-37) For the Lord will espouse the cause of his people, and bethink himself concerning his servants: When he seeth that their power is gone, and the guarded and fortified are no more, i.e., Ben David will not come until the informers will increase. According to others, until the pockets will be empty of a perutah. And some others also say unless they will renounce their hope to be redeemed, as it is said, And the guarded and fortified are no more. This is in accordance with R. Zera who found the Rabbis occupying themselves with the question of the Messiah, and he said to them, "I beg of you, do not cause the event to be removed further than it is, as there is a Baraitha that the following three come unexpectedly: Messiah, a discovery and a bite of a serpent.

(Devarim 32:36) "For the L-rd will judge His people, and over His servants yithnecham": When the L-rd judges (i.e., punishes) the nations, it is "joy" to Him, viz. (Proverbs 11:10) "and in the destruction of the wicked is rejoicing." And when the L-rd judges the righteous, there is "bethinking" before Him, as it is written "and over His servants, yithnecham," "nechamah" connoting "bethinking," viz. (Genesis 6:7) "for I (the L-rd) have bethought Myself (nichamti) for having made them," and (I Samuel 15:11) "I have bethought myself (nichamti) for having made Saul king."
