Rabbeinu Bahya
ברוך פרי בטנך, “blessed will be the fruit of your womb.” In this instance, the blessings accruing to the body are listed before such blessings as having abundance of food and drink, blessings which commence only with verse 5. When the curses are listed, the Torah begins with describing deprivations involving the people’s food supply (verse 17) before describing afflictions of the body (verse 20). This teaches the concern of G’d for us in that before harming us physically, He warns us by depriving us of something affecting our pocketbook, something not involving pain to our bodies.
Rashi
And a meal-offering...an ephah for a bull the meal-offering of the libations, an “ephah” for a bull. Now I do not know what this means, for the Torah stated (28:20): “three tenths for the bull.” It is possible that it means an “ephah” of flour from which we extract a tenth of fine flour from a “se’ah”, for the “ephah” is three “se’ahs”.
