הספרים. הני ⁠— אין, כלי פשתן ⁠— לא.

of barbers that are used to cover a person having a haircut, and body-drying towels may all be laundered on the intermediate days of a Festival. This statement implies that these garments, yes, they may be laundered, but other types of linen garments, no, they may not be laundered.

אמר ליה אביי: מתניתין אפילו דשאר מיני. אמר בר הידיא: לדידי חזי לי ימה של טבריה, דמפקי לה משיכלי דמני כיתנא בחולא דמועדא.

Abaye said to him: This is not a contradiction: The Mishnah is referring to garments made even of other types of materials; linen garments, however, may be laundered even when they serve other purposes. Bar Hedya said: I myself saw the Sea of Tiberias, the Sea of Galilee, to which basins full of linen garments were brought out to be laundered during the intermediate days of a Festival.

מתקיף לה אביי: מאן לימא לן דברצון חכמים עבדי, דלמא שלא ברצון חכמים עבדי.

Abaye strongly objects to this: This report cannot be adduced as proof for the halakha, for who says to us that they did this in accordance with the will of the rabbis? Perhaps they did it without the will of the rabbis.

מתני׳ ואלו כותבין במועד: קדושי נשים וגיטין ושוברין. דייתיקי, מתנה ופרוזבולין. איגרות שום ואיגרות מזון.

Mishnah: And these are the documents that may be written on the intermediate days of a Festival: Documents of betrothal of wives, through which bridegrooms betroth their brides; bills of divorce; receipts for the repayment of debts; wills [deyateiki]; deeds of gift; perozbolin, documents through which lenders authorize the courts to collect their loans on their behalf, thereby preventing the Sabbatical year from canceling their debts; letters of valuation, which were drawn up by the court when they valuated property and transferred it to the lender; and letters of sustenance, which were drawn up when one accepted upon himself to maintain another, e.g., his step-daughter.
