ויקב. כְּתַרְגּוּמוֹ "וּפָרֵשׁ", שֶׁנָּקַב שֵׁם הַמְיֻחָד וְגִדֵּף, וְהוּא שֵׁם הַמְפֹרָשׁ שֶׁשָּׁמַע מִסִּינַי (ספרא): ויקב — Translate this as the Targum does: ופרש “and he pronounced”, thus ויקב … ויקלל means that he uttered the Tetragrammaton and by so doing blasphemed. It was the “Proper Name” which he had heard on Mount Sinai (cf. Sifra, Emor, Section 14 2 and Jeremiah Targ.).
ושם אמו שלמית בת דברי. שִׁבְחָן שֶׁל יִשְֹרָאֵל שֶׁפִּרְסְמָהּ הַכָּתוּב לְזוֹ, לוֹמַר שֶׁהִיא לְבַדָּהּ הָיְתָה זוֹנָה: ושם אמו שלמית בת דברי AND HIS MOTHER’S NAME WAS SHELOMITH, THE DAUGHTER OF DIBRI, [THE TRIBE OF DAN] — it is to tell how praiseworthy Israel was that Scripture publicly mentions her name (exposes her), telling us implicitly that of all the women of Israel she alone was a harlot (Leviticus Rabbah 32 5).
שלמית. דַּהֲוָה פִּטְפְּטָה "שְׁלָם עֲלָךְ", "שְׁלָם עֲלֵיכוֹן", מְפַטְפֶּטֶת בִּדְבָרִים, שׁוֹאֶלֶת בִּשְׁלוֹם הַכֹּל: שלמית (connected with שלום “peace”) — she was so called because she was always babbling: “Peace be with thee”, “peace be with thee”, “peace be with you” — she used to continually babble with many words (she was a בת דברי) — she enquired after the health of everybody (Leviticus Rabbah 32 5).
בת דברי. דַּבְּרָנִית הָיְתָה, מְדַבֶּרֶת עִם כָּל אָדָם, לְפִיכָךְ קִלְקְלָה: בת דברי (from the root דבר “to speak”) — she was talkative — talking with any man, and in consequence of this she got into trouble.
למטה דן. מַגִּיד שֶׁהָרָשָׁע גּוֹרֵם גְּנַאי לוֹ, גְּנַאי לְאָבִיו, גְּנַאי לְשִׁבְטוֹ; כַּיּוֹצֵא בוֹ "אָהֳלִיאָב בֶּן אֲחִיסָמָךְ לְמַטֵּה דָן" (שמות ל"א), שֶׁבַח לוֹ, שֶׁבַח לְאָבִיו, שֶׁבַח לְשִׁבְטוֹ (ספרא): למטה דן OF THE TRIBE OF DAN — This mention also of the parent and tribe of the woman teaches us that the wrong doer brings shame upon himself, shame upon his parent, shame upon his whole tribe. Similarly we find the name of the tribe Dan mentioned to express praise; (Exodus 31:6) “Oholiab, the son of Ahisamach, of the tribe of Dan”, where the details of Oholiab’s descent imply praise for him, praise for his father and praise for his tribe (Sifra, Emor, Section 14 4).
