And know further that he must be very careful not to counsel Reuven to enter into partnership with Shimon if he knows of any loss that might result from their partnership (as when Shimon is very poor; how much more so, if he is not trustworthy). The same applies to [seeking] a match [shidduch] or a craftsman or the like. For even in the instances in which it is forbidden to go and speak rechiluth against Shimon, such as going and saying against him before Reuven, that he is in straitened circumstances, as mentioned above (and, likewise, in respect to a shidduch or a craftsman, each in its own way), it is forbidden to do so only by harming Shimon —
וְדַע עוֹד, דִּמְאֹד צָרִיךְ לִזָּהֵר שֶׁלֹּא לְיַעֵץ לִרְאוּבֵן, שֶׁיִּשְׁתַּתֵּף עִם שִׁמְעוֹן, אִם הוּא יוֹדֵעַ שׁוּם רֵעוּתָא {דבר רע}, שֶׁיּוּכַל לִהְיוֹת עַל יְדֵי שֻׁתְּפוּתָם, כְּגוֹן מִפְּנִי עֲנִיּוּתוֹ, וְכָל שֶׁכֵּן אִם אֵינֶנּוּ אִישׁ נֶאֱמָן כָּל כָּךְ. וְהוּא הַדִּין לְעִנְיַן שִׁדּוּךְ אוֹ אֻמָּן וּכְהַאי גַּוְנָא. דַּאֲפִלּוּ בָּאֳפָנִים, שֶׁאָסוּר לֵילֵךְ וּלְהַרְגִּיל עַל שִׁמְעוֹן, כְּגוֹן לֵילֵךְ וּלְסַפֵּר עָלָיו לִפְנֵי רְאוּבֵן שֶׁאֵינֶנּוּ תַּקִּיף בְּמַעֲמָדוֹ וְכַנַּ"ל. וּכְהַאי גַּוְנָא בְּשִׁדּוּךְ וּבְאֻמָּן, כָּל אֶחָד לְפִי עִנְיָנוֹ, הַיְנוּ, דַּוְקָא לֵילֵךְ וּלְהָרַע לוֹ, אָסוּר בְּכַמָּה גַּוְנִי מִטַּעַם רְכִילוּת.
