[Avodah] Purchasing produce grown by goyim in EY during Shmitta

[Moshe Feldman]

The Netziv is in HaAmek Davar Vayikra 25:4 (at the end) says that
Shevi'is is an issur connected to the cheftza of the land (in contrast
to Shabbos, which is an issur solely on the person) and consequently
there is a mitzva to purchase land from goyim so that the land rests.
Rav Yaakov Ariel, in his introduction to Katif Shevi'it (put out by
Otzar HaAretz), points out that therefore we should not purchase
produce from goyim who farm in Eretz Yisrael if this will cause them
to farm the land more intensively during Shevi'is.

Kol tuv,
Moshe
