An Abundance of Parnassah in the Merit of Meah Brachos

תמימם כבשים שבעת הלחם על והקרבתם" (גיח כ) "שנים ואילם אחד בקר בן ופר שנה בני

Rav Yaakov Tzvi Yalish, author of Melo Haro’im, explained: Reciting one hundred brachos each day brings down an abundance of food and parnassah to the world. This is alluded to by the fact that Dovid Hamelech, who instituted the mitzvah of meah brachos, was called “Bais Halachmi” (see Shmuel I 17:57), that in the merit of the brachos that he instituted that we recite there is bread and sustenance for the creations. This passuk also alludes to it: “Vehikravtem al halechem” – if you will bring על brachos each day, then Hashem will send you an abundance of parnassah from On High and you will never lack for bread. (Kol Yaakov)
