I’m not taking a position on the groceries and diapers exhortation, but this is the gemara he refers to (97A):
?”? (????? ??, ??) ?? ???? ?’ ??? [???’] ?? ???? ?? ???? ?? ???? ???? ????? ??? ?? ??? ?? ?? ????? ??????? ?”? ?? ??????? ???????? ?”? ?? ????? ????? ?? ???? ?”? ?? ???????? ?? ?????? ????? ???? ???? ????? ?????? ??? ???? ????? ??????
The Sages taught in a baraita: The verse states: �For the Lord shall judge His people and atone for His servants, when He sees that their power is gone and there is none shut up or left� (Deuteronomy 32:36). From the phrase �their power is gone� it is derived that the son of David will not come until informers will proliferate. Alternatively, the Messiah will not come until the number of students of Torah diminishes. Alternatively, the Messiah will not come until the peruta will cease from the purse. Alternatively, the Messiah will not come until they despair from the redemption, as it is stated: �And there is none shut up or left,� as though there were no supporter or helper for the Jewish people.
