Yevamot 74A

ונוהגין בשאר שני שבוע, ואין להם פדיון. מה שאין כן במעשר. שמע מינה.

Teruma and first fruits apply in all the years of the 7-year Sabbatical cycle, including the third and the 6th years, and they do not have the possibility of redemption, as once they are sanctified they may not be redeemed and rendered non-sacred. This is not the case with regard to second tithe, which applies only in the first, second, 4th, and fifth years of the cycle and which can be redeemed. The Talmud concludes: Learn from here that the tanna did not list all of the differences between second tithe and teruma.

תא שמע: נשתיירו בו ציצין המעכבין את המילה ⁠— הרי זה אינו אוכל לא בתרומה, ולא בפסח, ולא בקדשים, ולא במעשר. מאי לאו מעשר דגן, לא ⁠— מעשר בהמה.

The Talmud resumes its discussion of whether or not an uncircumcised man is prohibited from eating second tithe. Come and hear a proof with regard to this question from the following baraita: If shreds of flesh that invalidate the circumcision remain after the foreskin was removed, one may not eat teruma, nor the Paschal lamb, nor sacrificial food, nor tithe. What, is it not referring to tithe of produce, and so the dilemma is resolved? The Talmud refutes this suggestion: No, the tithe mentioned in this baraita is animal tithe. The baraita teaches that the meat of the animal tithe was forbidden to one who is uncircumcised.

מעשר בהמה היינו קדשים? וליטעמיך, מי לא תנן פסח וקתני קדשים!

The Talmud expresses surprise: Animal tithe is the same as sacrificial food, as it too is an offering the meat of which is eaten by the animal’s owner; why would the tanna single it out? The Talmud counters: And according to your reasoning that the baraita would not have singled out specific offerings, didn’t we learn in the baraita that an uncircumcised man may not eat the Paschal lamb, and yet it also teaches that the same halakha applies to sacrificial food?
