What do we learn from "Ashreichem Zore'ei Al Kol Mayim [Meshalechei Regel ha'Shor veha'Chamor]"?
Bava Kama 17a: Anyone who engages in Torah and Chesed merits the inheritance of two tribes. "Zore'ei" is Tzedakah - "Zir'u Lachem li'Tzdakah Kitzru l'Fi Chesed" (Hoshe'a 10:12). "Mayim" refers to Torah - "Hoy Kol Tzamei Lechu l'Mayim" (below, 55:1). They merit many children like Yosef, "Ben Poras Yosef Banos Tza'adah Alei Shor" (Bereishis 49:22) and wealth like Yisachar, "Yisachar Chamor Garem" (ibid., 14). Alternatively, their enemies fall in front of them, like Yosef, "[Bechor Shoro

What do we learn from "Meshalechei Regel ha'Shor veha'Chamor"?
Bava Kama 2b: "Meshalechei" refers to Regel (what an animal damages via walking normally).
Refer to 32:20:1:1-3.
Radak: There will be such satiation that you will send cattle and donkeys to graze in the fields 1 .
Normally, one would not do so, lest they damage grain. Amidst great satiation, you will not be concerned for this. (PF)
