Midrash su Aggeo 2:19

Variantly: "from the beginning of the year until the end of the year": Now are the fruits in the field from the beginning of the year until the end of the year? (The intent is that it is) in My domain to bestow blessing upon them (when they are) in the house as when they are in the field, as it is written (Ibid. 28:8) "The L-rd shall command unto you the blessing in your store-houses and in all to which you put your hand." And it is written (Chaggai 2:19) "Is there any more seed in the silo? Even the grapevine and the fig tree and the pomegranate tree have not borne their fruit, (but) from this day on, I will bless." They are in My domain to bestow blessing upon them, just as I bestow blessing upon them in the field. And mothiness and rot will not enter the fruit, and wine will not sour, and oil will not foul, and honey will not ferment. And whence do I derive (that this obtains) even in the storehouses? From (Devarim 28:3) "Blessed shall you be in the city (including the storehouses), and blessed shall you be in the field." Whence do I derive even the flour? From (Ibid. 5) "Blessed shall be your basket and your (kneading) bowl." Whence do I derive even in entering and in leaving? From (Ibid. 6) "Blessed shall you be in your coming in and blessed shall you be in your leaving." And whence do I derive even in eating? From (Ibid. 8:6) "And you shall eat and you shall be sated and you shall bless." And whence do I derive even when it descends into one's intestines? From (Shemoth 23:25) "and I shall remove sickness from your midst."
