Bava Metzia 116A

יתירא הוא, כיון דיתירא הוא ⁠– שדייה אריחים ורכב.

is superfluous and therefore includes other utensils as well. Since it is superfluous, apply it as another prohibition upon the lower and upper millstones.

אבל הכא, ״כי אם צלי אש״ לאו יתירא הוא, דמבעי ליה לכדתניא: בשעה שישנו בקום אכול צלי, ישנו ⁠– בבל תאכל נא. בשעה שאינו בקום אכול צלי ⁠– אינו בבל תאכל נא.

But here, with regard to the Paschal offering, the phrase “but roasted with fire” is not superfluous, as he requires it for that which is taught in a baraita: At the time when one is included in the mitzva to arise and eat the roasted Paschal offering, he is also included in the prohibition not to eat of it raw, but at a time when one is not included in the mitzva to arise and eat the roasted Paschal offering, he is not included in the prohibition not to eat of it raw either. Consequently, one who eats the Paschal offering at that time is not liable to receive lashes.

תניא כוותיה דרב יהודה: חבל זוג של ספרים וצמד של פרות ⁠– חייב שתים. זה בעצמו וזה בעצמו ⁠– אינו חייב אלא אחת.

§ The Talmud returns to the dispute concerning the lower and upper millstones. It is taught in a baraita in accordance with the opinion of Rav Yehuda: If one took as collateral barbers’ scissors [zog] or a pair of cows, he is liable to receive two sets of lashes. If he took this one blade of the pair of scissors by itself or that one cow by itself, he is liable to receive only one set of lashes. According to this tanna, he is not liable for the general prohibition.

ותניא אידך: חבל זוג של ספרים וצמד של פרות, יכול לא יהא חייב אלא אחת ⁠– תלמוד לומר ״לא יחבל ריחים ורכב״. מה ריחים ורכב שהן מיוחדין שני כלים ועושין מלאכה אחת, וחייב על זה בפני עצמו ועל זה בפני עצמו ⁠– אף כל דברים שהן שני כלים מיוחדים ועושין מלאכה אחת ⁠– חייב על זה בפני עצמו ועל זה בפני עצמו.

And it is taught in another baraita: If one took as collateral barbers’ scissors or a pair of cows, one might have thought that he is liable to receive only one set of lashes. Therefore, the verse states: “He may not take as collateral the lower or upper millstone,” which indicates that just as the lower and upper millstones are unique in that they are two distinct vessels and they perform one task together, and nevertheless one is liable separately for this and separately for that, so too, with regard to all items that are composed of two individual vessels, such as barbers’ scissors or a pair of cows, and they perform one task, he is liable separately for this and separately for that.
