Ein Ayahlessing for Those Who Know How to Appreciate the Future
Ein Aya Shabbat Chapter B Paragraph 226
Due to the sin of not giving terumot and ma’asrot (tithes to kohanim and levi’im, respectively), the skies are prevented from giving rain and dew … If they give, they are blessed, as the pasuk says: “Bring the ma’aser to the storehouse, and it shall be food in My house, and test Me in this … if I will not open up the skylights of the heavens and pour out limitless blessing” (Malachi 3:10) – until your lips get worn out saying “enough.”
