What We Will Soon Be Learning In Yeshiva

ליקוטי הלכות: הלכות הפקר ונכנסי הגר, הלכה ד:לב

In the future there will be completely holy yeshivot that will teach the study of holy emunah, which is an aspect of "I will yet again make make you dwell in tents, as in the days of the appointed season" (Hoshea 12:10).  Rashi comments on this pasuk and says that the days of the appointed season refer to the days when Yaakov Avinu sat in the tent (his yeshiva).  And Yaakov's whole yeshiva that learned with his sons and students, just as our Rebbeim z"l have said, learned only about holy emunah.  This is because the mitzvot were not yet given, and the focus of their learning was on the point of holy emunah in order to nullify all of the idolatry and heretical teachings and to continue and to plant and to establish in everyone's heart a complete and holy emunah.
