Demai 5:3 - 5:4

ומן הצוננים על החמה – even though he is tithing from the bad for the beautiful, he holds like Rabbi Illai who stated (Tractate Kiddushin 46b): A person who separates the priestly gift from the bad for the beautiful, his heave-offering is a [legitimate] heave-offering, and regarding doubtfully tithed produce, they (i.e., the Rabbis) permitted this even ab initio.

ואפילו מדפוסים הרבה – and we don’t suspect that perhaps yesterday the baker purchased the grain from someone who separates tithes and today [he purchased the grain] from someone who does not separate tithes, and if is found that he sets aside [for tithes] from that which is exempt for that which has an obligation, for the baker buys from one person, even though he makes it from many [different] molds.

רבי יהודה אוסר – when both of them were from yesterday evening or both of them are from today, Rabbi Yehuda agrees with Rabbi Meir , that even if they come from different molds, they are permitted, because he doesn’t worry about molds. But one from yesterday and another from today, even from one mold, he forbids as I state, etc.: (“Yesterday’s grain may have from one man and today’s grain from another” – i.e., yesterday’s wheat may have been tithed while that of today was not tithed, or vice versa).

ר' שמעון אמסור בתרומת מעשר - for even if both of them were from today or both of them were from yesterday, since they are from two molds, we state that he purchase the grain from two people and perhaps one of them tithed and the other did not [tithe] and it is found that he is separating from that which is exempt for that which is one with an obligation.

ומתיר בחלה – for regarding the dough offering, everyone agrees that even that of yesterday with that of today, and even from two molds, that alternatively he bought from two people, we don’t worry for with the baker he is obligated to separate Hallah in that he formed the dough by rolling.

פלטר – he that purchases many loaves at one time from the bakery shop and afterwards sells them one-by-one in the marketplace.

מעשר מכל דפוס ודפוס דברי רבי מאיר – for Rabbi Meir holds that a bakery shop that purchases from two or three bakers, and we say that this mold he brought from this baker and that mold [he purchased] from another baker. But Rabbi Yehuda holds that he bought [only] from one baker and even though they (i.e., the loaves) are from different molds, all of them are from one baker. Therefore, if all of them were from yesterday or all of them from today, he separates tithes from one to cover all of them according to the law of the baker.

מנפול (a trading mart enjoying a monopoly)– he purchases from many bakery shops and sells to others, and since he is accustomed to purchase from many people, a person who purchases from him tithes for each and every one. And the Halakha is according to Rabbi Yehuda.
