Moed Katan 13B

והתניא: מביאין כלים מבית האומן, כגון כד מבית הכדר, וכוס מבית הזגג. אבל לא צמר מבית הצבע, ולא כלים מבית האומן. ואם אין לו מה יאכל ⁠— נותן לו שכרו ומניחו אצלו. ואם אינו מאמינו ⁠— מניחו בבית הסמוך לו. ואם חושש להם שמא יגנבו ⁠— מפנן לחצר אחרת, ואם אינו מאמינו ⁠— מביאן בצנעה בתוך ביתו.

And so it is taught in a baraita: One may bring home utensils from the house of a craftsman; For example: a jug from the jug-maker's house and a cup from the glass-blower’s house, as they will be used on the Festival itself. But he may not bring home wool from the dyer’s house or utensils from the craftsman’s house, as they are not needed on the Festival. But if the craftsman has nothing to eat, he may give him his wages during the Festival week and leave the utensil with him. And if he does not trust the craftsman to properly safeguard his utensil, he may take the utensil from the craftsman and leave it in a house near him. And if he is concerned about his utensils lest they be stolen, he may move them to another courtyard. And if he does not trust the owner of the other courtyard, he may bring them into his house discreetly.

תרצת מביאין, מוליכין קשיא, דקתני: אין מביאין, וכל שכן שאין מוליכין! אלא: מחוורתא כדשניין מעיקרא.

The Talmud comments: You have adequately explained the contradiction between the mishnayot about whether one may bring home utensils from the house of a craftsman. The Mishnah that permits it can be understood as referring to a case where the craftsman is not to be trusted. But the Mishnah in Pesaḥim also states that one may take utensils to the house of a craftsman, and this is difficult, as the Mishnah above teaches: One may not bring home utensils from the house of a craftsman. And this indicates that all the more so, one may not take utensils from his house to that of the craftsman. Rather, it is clear as we answered initially that one Mishnah is referring to the eve of Passover and the other to the intermediate days of a Festival.
