Mishnayos Eduyos Perek 8 Mishnah 4

איל קמצא – a form of locust. The Aramaic translation of “like locusts” is “like a species of locusts.”

דכן – it is clean and permitted to eat.

ועל משקה בית מטבחייא – the blood in the slaughterhouse of the Temple courtyard.

דאינון דכיין – there is one who says that they are completely pure, for the defilement of liquids is not from the Torah but rather the Rabbis are those who decreed upon them defilement, and on these they did not decree. And there is another opinion that these are pure from making others impure, but they are impure of themselves and there is, from the Torah, defilement for liquids, to become defiled and the Rabbis were not able to make pure what the Torah had defiled.

ועל דיקרב למיתא מסאב – this is how it should be understood (Talmud Avodah Zarah 37b), that whomever definitely touches a corpse is unclean. But there is a doubt, even a grave defilement of the dead is pure, and all the more so, defilement [via a contact with] a reptile is light. And a doubtful impurity in the public domain comes to permit. And even though a doubtful impurity in the public domain is pure according to the Torah, for prohibition of doubtful defilement we derive from the Sotah/suspected adulterous woman, for the Bible derives it with the language of defilement (Numbers 5:13): “and she keeps secret the fact that she has defiled herself, the Biblical verse informs us that on that which is doubtful, she is prohibited, and just as the case of the Sotah/suspected adulterous woman is in the private domain, and there is no hiding in the public domain, so doubtful defilement is not other than in the private domain, nevertheless before Yosi ben Yoezer came, they would say, it is the Halakha but we don’t teach thus. And he came and testified that we do teach as such ab initio, to make pure all doubtful defilement in the public domain.

וקרי ליה יוסי שריא – because he permitted three things that they (i.e., the Rabbis) would practice a prohibition on them. For any Jewish court that permits three things where their permit is not simple, they would call it, a permitting/absolving Jewish court.
