Seeing as the Torah has already stated that no crops will grow, what is the significance of the phrase "Ve'sam la'Rik Kochachem"?
Rashi: It is one thing for nothing to grow if one did not plow, sow, weed, prune and dig, but quite another, if one expends time and energy to plow, sow, weed, prune and dig, and along comes a drought and destroys everything.
Rashbam: The Pasuk is referring (not to the input of the owners, but) to the land, which will not give of its strength to them.
What are the implications of "Artz'chem" and the word "Yevulah" (See Sifsei Chachamim)?
Rashi and Targum Yonasan: This informs us that even what one plants in the planting season will not grow.
Why does the Pasuk add the "ha'Aretz"?
Rashi: To inform us that the earth will prevent the fruit from forming in its right time.
What are the connotations of the phrase "ve'Eitz ha'Sadeh Lo Yiten Piryo"?
