פּירוש אויף דברים 11:15

ונתתי עשב בשדך AND I WILL GIVE GRASS IN THY FIELD [FOR THY CATTLE] in thy field: so that you will not need to lead them to distant pasture grounds. Another explanation: it means that you will be able to cut your grain all the rainy season and cast it before thy cattle as fodder, and if you withdraw your hand from it (stop doing this) only thirty days before the harvest, it will not give you less of its corn than if you had not fed your cattle with it (as is implied by ואכלת ושבעת, you will eat to the full) (Sifrei Devarim 43:2).

you will eat and be satisfied referring to the abovementioned “grain and wine” [: 14], not the more proximate grass in your fields .

AND THOU SHALT EAT AND BE SATISFIED. “This is another blessing, meaning that there will be a blessing on the bread within your stomach, and you eat and be satisfied.” This is Rashi’s language and Rabbi Abraham ibn Ezra commented: “And thou shalt eat and be satisfied. This refers back to thy corn, and thy wine, and thine oil [mentioned in the preceding verse], not to the grass in thy fields which is near [in the same verse].” The correct interpretation in my opinion is that it refers to everything: “and thou shalt eat and be satisfied with the corn, wine, and oil, and also the sheep and cattle [will eat and be satisfied with the grass in the field].” And in the Sifre we find:³²⁶Sifre, Eikev 43. “And thou shalt eat and be satisfied, when your cattle eats and is satisfied, it works the ground [with strength], and so it is said, and much increase is by the strength of the ox.³²⁷Proverbs 14:4. Another interpretation: [And thou shalt eat and be satisfied] from the young [of the cattle]. Although there is no proof of this, yet there is an indication, for it says, And they shall come and sing in the height of Zion, and shall flow unto the goodness of the Eternal, to the corn, and to the wine, and to the oil, and to the young of the flock and of the herd etc.”³²⁸Jeremiah 31:11. This is the correct interpretation.

ואכלת ושבעת AND THOU SHALT EAT AND BE SATISFIED — This is quite another (a separate) blessing; it means that a blessing will be on the bread within the stomach (see Rashi on Leviticus 25:19). השמרו לכם
