Demai 5:1 - 5:2

הלוקח מן הנחתום – when the baker [who does not observe certain religious customs regarding tithing] sells [loaves of bread] in large measures (i.e., bulk), a person who purchases from him is obligated to make things legally fit for use by giving the priestly dues, and the baker is exempt [from tithing]. But surely, in that it is taught in the Mishnah above in chapter 2 (in Mishnah 4) that bakers are obligated to separate so that there is a measure for a limit for the heave-offering of tithe [which is given to the Levite] and Hallah [given to a Kohen, usually one forty-eighth for a commercial baker as opposed one twenty-fourth for a private person]. There (i.e., in Tractate Hallah, Chapter 2, Mishnah 4) it is speaking about a person who sells in small quantities (i.e., retail) because he profits greatly, they {i.e., the Rabbis) placed upon him [the responsibility] to tithe; alternatively, because the young children that purchase from someone [who sells] in small portions (i.e., retail), in order that they will not consume eatables forbidden pending the separation of sacred gifts, they (i.e., the Rabbis) placed upon him [the obligation] to make things legally fit for use by giving the priestly dues. The terms מדה גסה/large quantities and דקה/small quantities is explained at the end of the second chapter [of Tractate Demai, Mishnah 5].

נואל כדי תרומת מעשר – which is one [part] in one-hundred (i.e, 1/100) and so he can give Hallah [to the Kohen] one in forty-eight [parts] (i.e., 1/48). But he should not separate them from the loaf that he purchased from the baker, but rather established for them a place and leaves them attached in their place.

אחד ממאה ממה שיש כן – from everything that is here, implying, even with according to the quantity of Hallah that he separated is made into a tithe, and it is found that he separates the tithe (i.e., First Tithe) even from the Hallah portion.

ושאר מעשר – that is another nine [parts] that are next to it, he established a place for the entire [First] Tithe, and that one that one-part that I called it by the name of “[First] Tithe} at first is made into the heave-offering of the tithe (i.e., that which the Levite gives to the Kohen) on the nine [parts] that are near it.

והשאר חלה – one out of forty-eight [parts] (i.e., 1/48) that I separated out as Hallah [for the Kohen].

ומעשר שני בצפונו או בדרומו – he establishes for himself a place and afterwards he redeems it, but he does not need to add the [additional] one-fifth.

נוטל אחד משלשים ושלש ושליש – which is one-third from one-hundred (i.e., thirty-three and one-third). And the Seah that he takes there has three thirds, two of them for the heave-offering which is two from one-hundred (i.e., 2/100 or 1/50) and one for the heave-offering of the tithe which is one out of one-hundred (i.e., 1/100). And he states regarding that Seah that he took one out of one-hundred that is here, whether all of it, which is a third of that Seah.

הרי הוא בצד זה חולין – its explanation: it should remain unconsecrated like it is now in is eatables that are forbidden pending the separation of sacred gifs at the side of the two-thirds that are with him, and the rest, which is two third-thirds will be heave-offering on everything.

מהחולין שיש כאן – that is the third that I spoke of that should remain unconsecrated, behold this is at the side of that tithe.

ושאר מעשר – that is another nine next to this one-third, those ten thirds will be a tithe on the one-hundred thirds. And not exactly ten, but rather a bit less according to the when we reach the [various] years of Terumah.

זה שעשיתי מעשר – that is the one-third that he designated by name to be Tithe first is made the heave-offering of the tithe on the nine thirds. But not a complete third, but rather missing a small amount. And for this it is stated from that unconsecrated that is here, which implies, but not all of the unconsecrated produce. But our Mishnah is like Abba Eleazar ben Gomel who stated at the end of the chapter כל הגט /”All bills of divorce” (Tractate Gittin 31a): just as the owner has the permission to separate the priestly gift of the Great Terumah (i.e., Terumah Gedolah – which is 1/50 which goes to a Kohen), so too he has the permission to separate the heave-offering of the tithe (i.e., the one-tenth of which the Levite ordinarily gives to the Kohen after receiving the First Tithe). And he is also permitted to separate the heave-offering of the tithe through a generous estimation in the chapter "כל המנחות באות מצה"/”All meal offerings are brought unleavened” (in the fifth chapter of Menahot 54b-55a), therefore, that one-third that he separates [to be donated] from the whole even though is was appropriate to be missing a little bit, with a generous portion/good will, he separates [these tithes] and it is permitted.
