(Mishnah): If produce was for use as animal fodder or to tie bundles; or to tie garlic or onions; there is no Shichechah.

Any vegetables that are hidden in the ground, such as Luf (a species of onion), garlic and onions - R. Yehuda says that there is no Shichechah; the Chachamim say that there is Shichechah.

(Gemara) (R. Yona): Not only if it was used but even if it was cut to be used as animal fodder etc. there is no Shichechah.

(Mishnah in Bava Kama): If a person set fire to a haystack and there were utensils inside it, R. Yehuda says that he must pay for whatever was inside it and the Chachamim say that he must only pay for the produce (whether it was wheat or barley).

Question: The opinion of R. Yehuda seems to have switched - there he obligates for (burning) something hidden; here, he exempts something hidden from Shichechah?

Answer: There, the pasuk states (Shemos 22:5), "and a stack of grain or standing grain or the field will be consumed" - if standing grain is mentioned, why mention a stack of grain? Rather, it is written to include something hidden. Here (Shichechah), the word 'your field' implies that which is exposed, but not something hidden.

Question: The opinion of the Rabbanan seems to have switched - there (in Bava Kama) they exempt for burning something hidden; here, they obligate something hidden in Shichechah?

Answer: There, the pasuk compares standing grain to the field - just as the field is exposed, so too it applies to anything else exposed. But here (Shichechah), 'your field' implies exposed, this excludes something hidden; 'your harvest' implies exposed, which excludes something hidden - this is an exclusion following an exclusion which we are required to use as an inclusion - to include something hidden.

(Mishnah): If one harvested at night and binds sheaves or one who is blind - there is Shichechah. And if he intended to only take the large ones (and come back later for the small ones), there is no Shichechah. If he said, "I am harvesting on condition that whatever I forgot, I will take" - there is Shichechah.

(Gemara): Learn the Mishnah as - 'one who harvested at night, one who binds sheaves at night and a blind person, whether in the day or at night'.

(R. Yona): The Mishnah does not only mean if he intended to only take the large ones (and come back later for the small ones), but even vice-versa, because just as when he comes back for the small ones, he will notice any large one left behind, so too if he comes back for the large ones, he will notice any small one left behind.

The Mishnah taught - If he said, "I am harvesting on condition that whatever I forgot, I will take" - there is Shichechah. This is because he is making a condition against that which is written in the Torah - such a condition is not valid.
