[Avodah] Borders of Israel

[Micha Berger]

The mishnah Demai 1:3 speaks of the Keziv onward, which was conqured in
the days of Yehoshua and not those of Ezra, as not being subject to demai.

Moreso, we lean a couple of blatt later at the begining of pere 2 of the
Y-mi, that lands that weren't conqured in the days of Ezra but were part
of EY by the days of the tannaim are also not subject to demai.

Which would seem to put to rest ideas that growth of Israel's borders
today would impact the range of lands covered by mitzvos hateluyos
baaretz.

HOWEVER...

Demai 2:1 (8b vilna, near the bottom), gives R' Imi's (Alef-yud-mem-yud,
can't be "R Ami") shitah that "mema'alei masin kemi sheniskhavshu". Thus,
any city that pays taxes to Tzur is considered part of Tzur WRT demai.

Is this because R' Imi is choleiq the above, and holds that later kibush
-- and even implied kibush -- does extend borders?

Or perhaps -- just thinking out loud -- it's because the laws of which
vegetables you can assume are local depends on trade. The fact that
they taxes to Tzur imply being under their fiscal umbrella. Which would
imply that they get the same set of vegetables shipped in from the same
places. However, then what's "kemi sheniskhavshu"?

Thoughts?

Tir'u baTov!
