Mishnayos Menachos Perek 1 Mishnah 2

זר ואונן וטבול יום כו' – all of them are explained in the Second Chapter of [Tractate] Zevakhim [Mishnah 1], and we prove them from Scriptural verses that their Divine Service is invalid.

ערל – a Kohen whose brother died on account of ritual circumcision.

יושב – that we require to stand to minister/serve [before God].

על גבי כלים כו' – that we require that there will not be anything that divides/cuts off between him and the floor.

בן בתירא אומר יחזיר – the handful of the meal-offering which the priest takes to be put on the altar into the meal-offering.

ויחזיר ויקמוץ בימין – and same law applies to all of these invalidates that are considered in our Mishnah, Ben Beteyra holds that if someone transgressed one of them and took a fistful, he should return the handful of the meal-offering to its place and a kosher/fit Kohen should take a handful of the meal-offering to be put on the altar into the meal offering. But the Halakha is not according to Ben Beteyra.

עלה בידו צרור – it was found that the handful of meal-offering which the Kohen takes to put on the altar was missing the place of the stone or a grain of salt or a particle of frankincense, for prior to taking a fistful of meal-offering he singles out all of the frankincense to one side and takes a handful of meal-offering and afterwards collects it and places with the handful of meal-offering and burns everything. But if he happens upon a grain of salt or a particle of frankincense, the handful of meal-offering is missing according to the place of the particle [of frankincense].

מבורץ – full and overflowing.

שקמצו בראשי אצבעותיו – he did not stretch them over the entire palm of his hand.

פושט את אצבעותיו על פס ידו – the sides of his fingers enter into the flour and he brings in the flour into his hand and smooths it with his small finger so that the flour will not go outside of the fistful and he he smooths it with his thumb that the flour would not leave outside of his finger. And this he had to do with meal-offerings prepared in a pan (i.e., fried in a flat pan) or [a meal-offering] prepared in a deep pan (i.e., fried in a container full of oil) that their creations are baked and after they their baking, he crumbles it and takes a fistful. But it is impossible to crumble it so much into thin pieces, for they would not go forth from the fistful, therefore, he smooths them with his thumb from above and with the small finger (i.e., pinky) from below. And these were of the most difficult [acts] of Divine service that were in the Temple. That in this great difficulty one is able to compare that he would not be missing or have too much. And Maimonides wrote, that the words of the one of said that this is a difficult [act] of Divine Service were set aside, and he explains and he takes a fistful of the meal-offering as people would take fistfuls that is mentioned in the Gemara [i.e., Tractate Menahot 11a], that he fills his palm from it in the manner that people fill their hands from what they take in their hands. But I say, that that the explanation is not as how people take a fistful [of meal-offering] but rather, causes the sides of his fingers to enter into the flour that he brings in the flour with the sides of his fingers into his hand, but he doesn’t take the flour but rather fills three of his fingers until the palm of his hand and not further, in order that it will be cutting through from end to end and burst forth and come out, he smooths it from below with his small finger (i.e., pinky) and from above with a thumb. And that the words of the one who said that this is a difficult act from the difficult acts of Divine Service that is in the Temple are not set aside and the method of the Gemara is like m words. And such all of my teachers have explained it.
