Malachi 3:7-12

Even from the yamei avoteichem ye are gone away from Mine chukkim, and have not been shomer over them. Return unto Me, and I will return unto you, saith HASHEM Tzva'os. But ye said, Wherein shall we return? Will a man rob G-d? Yet ye have robbed Me. But ye say, Wherein have we robbed Thee? In ma'aser (tithes) and terumah (offerings, contributions). Ye are cursed with a me'erah (curse); for ye have robbed Me, even this whole Goy (nation). Bring ye kol hama'aser (all the tithes) into the Beis HaOtzar (House of the Treasury), that there may be teref (food) in Mine Beis, and prove Me now herewith, saith HASHEM Tzva'os, if I will not open you the windows of Shomayim, and pour you out a brocha, that there shall not be room enough to receive it. And I will rebuke the devourer for your sakes, and he shall not destroy the p'ri ha'adamah; neither shall your gefen cast her fruit before the time in the sadeh, saith HASHEM Tzva'os. And kol HaGoyim shall call you blessed; for ye shall be an Eretz Chefetz, saith HASHEM Tzva'os.
