How could wheat fall with rain?

Rashi: A ship with wheat was absorbed in clouds.

Tosfos: If the wheat was from Chutz la'Aretz, why should it be Kosher for Shtei ha'Lechem?!

Daf Al ha'Daf citing Teshuvas Chasam Sofer (OC 128): Perhaps we discuss when we know that the wheat came from Eretz Yisrael.

Ha'Boneh: We offer Shtei ha'Lechem to thank Hash-m for bringing bread from the land - the land given for a gift to Yisrael. So we say in Viduy Bikurim "ha'Adamah Asher Nasata Li." The question is because this wheat did not come from the land of Yisrael. Some say that Shtei ha'Lechem are for the two kinds of food that Hash-m gave to Yisrael then - food for the body in Eretz Yisrael, and food of the Nefesh - the Torah, from Har Sinai. According to Rashi, the wheat was from the land and from Shamayim!

Tosfos: It was a miracle, like the meat that fell from Shamayim (Sanhedrin 59b).

Daf Al ha'Daf: The Rambam (Hilchos Ma'ase ha'Korbanos Perek 7) holds that if he brought wheat that fell from Shamayim, b'Di'eved it is Kosher. He holds that what comes from a miracle is like what comes from nature. Yagdil Torah (9, 62-67, Siman 48) says that if so, one may write a Sefer Torah, Tefilin or Mezuzah on skin of an animal created via Sefer Yetzirah. However, SHLaH (Vayeshev) wrote that such an animal does not require Shechitah; R. Chanina and R. Yoshiyah created one every Erev Shabbos (Sanhedrin 65b). Yosef did not know that his brothers did so, therefore, he suspected them of Ever Min ha'Chai. If so, it is not considered a Behemah, so one may not write a Seforim on its skin. The meat that Shamayim roasted for Adam ha'Rishon did not have the law of meat (ibid. 59b). The Imrei Emes explained that it was not Ever Min ha'Chai, but it was meat. The miracle of the oil of Chanukah was natural oil, just a small Kli contained a large amount (NOTE: or, it burned longer than it should have. - PF)

Daf Al ha'Daf citing Merafsin Igra (Emor): One may not benefit from a miracle (Ta'anis 24b). If so, one may not eat the wheat that fell. If so, it is Pasul for Shtei ha'Lechem, for it is not mi'Mashke Yisrael" (from something that Jews may eat)! R. Y. M. Feinstein answered that the Isur to benefit from miracles is mere Midas Chasidus. Rashi in Ta'anis said 'it is proper to distance from benefiting from miracles .' Merafsin Igra said, even if it is forbidden, the Isur is not on the food; it is on the person. Rashi said, if a miracle is done for someone, they deduct from his merits. (It seems that one may eat it for a Mitzvah.)

Daf Al ha'Daf: Nahar Esh (p. 209, 86) says that most laws of the Torah do not apply in practice, even among those Mitzvos that apply nowadays. Much of Kodshim addresses the laws of Pigul. Did a Kohen ever intentionally offer a Korban with intent to eat after the time? B'Shogeg it is not Pigul! (NOTE: If a Kohen was Mefagel b'Shogeg, he is exempt. This is an enactment for Tikun ha'Olam (i.e. lest he not inform us - Gitin 53b). If b'Shogeg it is not Pigul, why must we know?! - PF) The Kares is only if all Avodos ha'Dam were with such intent! Also here, surely wheat never fell with rain! We learn Torah to understand Hash-m's will, even if such a case will never arise.

How could the wheat be used for Shtei ha'Lechem? Perhaps Nochrim harvested it!

Daf Al ha'Daf: Teshuvas Chasam Sofer (OC 128) says that Jews must harvest the Omer; this is not required for Shtei ha'Lechem. However, perhaps it is from Chutz la'Aretz. Most of the world is Chutz la'Aretz! Perhaps we discuss when we know that the wheat came from Eretz Yisrael. It must come "mi'Moshvoseichem (from where you dwell)."
