Zevachim 24A

וכל שני כתובים הבאין כאחד ⁠– אין מלמדין.

And any two verses that come as one do not teach their common aspect to similar cases. Therefore, one cannot assume that analogous prohibitions carry penalty of death at the hand of Heaven as well.

ולמאן דאמר מלמדין ⁠– שתויי יין הוה ליה שלישי, ושלשה לדברי הכל אין מלמדין.

And even according to the one who says that they do teach their common aspect, the prohibition against service by those who drank wine also contains explicit mention of death at the hand of Heaven and constitutes a third verse. And all agree that 3 verses that come as one do not teach their common aspect.

עומד על גבי כלים, על גבי בהמה, על גבי רגלי חבירו ⁠– פסול. מנלן? דתנא דבי רבי ישמעאל: הואיל ורצפה מקדשת וכלי שרת מקדשים; מה כלי שרת ⁠– לא יהא דבר חוצץ בינו לבין כלי שרת, אף רצפה ⁠– לא יהא דבר חוצץ בינו לבין הרצפה.

§ The Mishnah teaches that one who is standing upon vessels, or upon an animal, or upon the feet of another, is unfit to perform rites. The Talmud elaborates: From where do we derive this? This is derived as the Sage from the school of R' Yishmael taught: Since the floor of the Temple courtyard sanctifies the priest to perform the service, and service vessels, i.e., priestly vestments, also sanctify him, one may draw a comparison between the two: Just as with regard to service vessels, nothing may interpose between the priest and the service vessel, so too with regard to the floor, nothing may interpose between the priest and the floor.

וצריכא; דאי אשמעינן כלי ⁠– משום דלאו מינא דבשר נינהו; אבל בהמה, דמינא דבשר הוא ⁠– אימא לא. ואי אשמעינן בהמה ⁠– דלא מינא דאדם הוא; אבל חבירו, דאדם הוא ⁠– אימא לא; צריכא.

The Talmud adds: And each of the 3 cases mentioned in the Mishnah is necessary. As, had the Mishnah taught us only that a vessel interposes between the priest’s feet and the floor, one might have thought that this is only because it is not a type of flesh, but with regard to an animal, which is a type of flesh, I will say that it does not constitute an interposition. And had it taught us only that an animal interposes, one might have thought that this is only because it is not of the human species, but another person, who is human, I will say that he does not interpose. Therefore, each is necessary.
