How great is the issur of lashon hara, which the Torah has forbidden even if true and in all modes. For not alone if he is careful to speak it only in private and to insist that it not be revealed to him [who is spoken about] is it forbidden, [for through this he also brings a curse upon himself, viz. (Devarim 27:24): "Cursed be he who smites his neighbor in secret"], but even if he knows that he would speak it even to his face, or actually speaks lashon hara to his face, even so it is forbidden and called "lashon hara." And in one respect, the issur is greater "to his face" than not to his face." For in his presence, aside from the issur of lashon hara, he [the speaker] clothes himself with the trait of brazenness and audacity, and arouses more strife thereby. And very often this leads also to the "whitening of (the other's) face (in shame)," as we have enlarged upon in the introduction concerning the negative commandment of (Vayikra 19:17): "Do not bear sin because of him."
כַּמָּה גָּדוֹל אִסוּר לָשׁוֹן הָרָע, שֶׁאְסַרְתּוֹ הַתּוֹרָה אֲפִלּוּ עַל אֱמֶת וּבְכָל גַּוְנֵי, דְּלֹא מִּבָּעֵי אִם הוּא שׁוֹמֵר אֶת עַצְמוֹ לְסַפֵּר עָלָיו בַּסֵתֶר וּמַקְפִּיד עַל זֶה שֶׁלֹּא יִתְגַּלֶּה לוֹ דְּאָסוּר, שֶׁעַל יְדֵי זֶה מְקַבֵּל עַל עַצְּמוֹ גַּם כֵּן אָרוּר, כְּמָה דִכְתִיב "אָרוּר מַכֶּה רֵעֵהוּ בַּסָתֶר", אֶלָּא אֲפִלּוּ אִם הוּא מְשַׁעֵר בְּעַצְּמוֹ, (א) שֶׁהָיָה אוֹמֵר דָּבָר זֶה אַךְ בְּפָנָיו, אוֹ שֶׁהוּא מְסַפֵּר לָשׁוֹן הָרָע על חֲבֵרוֹ בְּפָנָיו מַמָּשׁ, גַּם כֵּן אָסוּר וְלָשׁוֹן הָרָע מִקְרֵי, וּבְצַּד אֶחָד גָּדוֹל אִסוּרוֹ בְּפָנָיו מִשֶּׁלֹּא בְּפָנָיו, דִּבְפָנָיו, לְבַד אִסוּר לָשׁוֹן הָרָע, הוּא מַלְבִּישׁ אֶת עַצְּמוֹ עַל יְדֵי זֶה בְּמִדַּת הָעַזּוּת וְהַחֻצְפָּה וְהוּא מְעוֹרֵר יוֹתֵר מְדָנִים עַל יְדֵי זֶה, וְכַמָּה פְּעָמִים בָּא עַל יְדֵי זֶה גַּם כֵּן לִידֵי הַלְבָּנַת פָּנִים, וּכְמוֹ שֶׁהֶאֱרַכְנוּ לְעֵיל בַּפְּתִיחָה בְּלָאו דְּ"לֹא תִשָּׂא עָלָיו חֵטְא". עַיֵּן שָׁם.
