Shekalim 7:7 - 8:1

שיהיו הכהנים נאותין בהן – specifically regarding the consuming of the sacrifices. But, regarding the eating of non-holy things, even the salting of non-holy things that are eaten in the Temple courtyard with the sacrifices in order that the sacrifices would be eaten with satiation, they don’t enjoy them (i.e., the salt and the wood).

שלא היו מועלין באפרה – for from the Torah, they cannot commit religious sacrilege with its ashes, as it is written (Numbers 19:9): “[A man who is clean shall gather up the ashes of the ow and deposit them outside the camp in a clean place, to be kept for water of lustration for the Israelite community.] It is for cleansing.” Through it they commit religious sacrilege but they don’t commit religious sacrilege through its ashes, but since they saw that they were despising it, they decreed that through its ashes is religious sacrilege because they saw that they separated themselves from the doubt of sprinklings, they established it as from the Torah.

ועל הקינין הפסולות – those obligated for bird-offerings they bring the money and place it into shofar-shaped chest and the Jewish court takes the money and purchases with them the bird-offerings and the owners go to them and rely upon the Jewish court that they will offer their bird-offerings but if the birds flew off or were found to be invalid, it is a condition of the Jewish court that they would take others from the monies of the chamber and give possession to the owners and fulfill through the their religious obligation.

רבי יוסי אומר – the one who regularly supplied the bird-offerings who fixed the price with the treasurers to sell them all the bird sacrifices that are needed, he is obligated to exchange all that is found in them something invalid, as is taught in the Mishnah (nine) above in the chapter “The Sacred Contributions”/"התרומה", he doesn’t receive his funds until the Altar is satisfied. But if the wine fermented or the fine flour became wormy, they return it to him and he returns the money, and the Halakha is according to Rabbi Yosi, for this is what we say in the Jerusalem Talmud that it is a condition of the Jewish court that whomever supplies the bird offerings supplies that which becomes lost or that is invalid.

כל הרוקין הנמצאים בירושלם אהורים – and we do not encourage the spittle of a man or woman suffering from an emission because they defile humans and utensils because we follow after the majority.

חוץ משל שוק העליון – because heathen launderers were found there and the Sages decreed concerning the heathens that they would be like men with a flux in all their matters, and their spittle is ritually impure. But there are those who state that that since the Upper Market did not have the benefit of the crossing found there (i.e., “foot traffic”) and men and women with a flux were alone and distanced themselves from other people that were found there.

שבאמצע טמאים – because men and women with a flux are frequently there and walk in the middle of the roads, and the ritually pure individuals remove themselves to the sides of the roads – in a place where there is not much walking found, and are careful of all ritually impure that they should not come in contact with them, but at the time of the Festival, when the majority of Jews are ritually pure, the ritually impure remove themselves to the sides so that they do not defile the people, and the ritually pure walk in the middle of the roads; therefore, at the time of the Festival, the spittle that is found in the middle of the road is ritually pure, but that which is on the sides is ritually impure, and the Halakha is according to Rabbi Yosi.
