What Brachah is inherent in "Venasati Eisev be'Sadcha li'Vehemtecha"?
Rashi #1: There will be sufficient grazing grounds near home, and you will not need to take your animals to the desert to graze.
Rashi #2: You will be able to cut your crops throughout the winter season to feed them to your animals, and to withdraw thirty days before the harvest season, and it will re-grow fully in time for the harvest.
What do we learn from "Ve'achalta Vesava'ta"?
Rashi and Ramban #1 (citing Rashi): It is an independent B'rachah 1 - that the food will be blessed inside your stomachs, the food that you eat will satiate you and you will not be hungry.
Ramban #2 (citing the Ibn Ezra): It is written with reference to "Degancha, ve'Siroshcha ve'Yitzharecha" (mentioned in the previous Pasuk). 2
Ramban #3: It refers to everything that precedes it - to "Degancha, ve'Siroshcha ve'Yitzharecha" and to the sheep and cattle mentioned in this Pasuk (all of which you will eat and be satiated).
Ramban #4 (citing the Sifri): 'When your animals have enough to eat, they will help work the land (thereby enabling abundant crops to grow, 3 as a result of which you will eat and be satisfied'.
Ramban #5: The Pasuk means that you will eat the children of the animals mentioned earlier and be satisfied. 4
Brachos, 40a: One may not eat before feeding his animals [that depend on him for food] -- "v'Nasati Esev b'Sadcha li'Vhemtecha", and afterwards "v'Achalta v'Savata."
