פּירוש אויף במדבר 27:7

כֵּ֗ן בְּנ֣וֹת צְלָפְחָד֮ דֹּבְרֹת֒ נָתֹ֨ן תִּתֵּ֤ן לָהֶם֙ אֲחֻזַּ֣ת נַחֲלָ֔ה בְּת֖וֹךְ אֲחֵ֣י אֲבִיהֶ֑ם וְהַֽעֲבַרְתָּ֛ אֶת־נַחֲלַ֥ת אֲבִיהֶ֖ן לָהֶֽן׃

גערעכט טענהן די טעכטער פֿון צלָפֿחָדן: געבן זאָלסטו זײ געבן אַן אײגנטום פֿון אַ נחלה צװישן די ברידער פֿון זײער פֿאָטער, און זאָלסט מאַכן איבערגײן די נחלה פֿון זײער פֿאָטער צו זײ.

כן בנות צלפחד דברת THE DAUGHTERS OF ZELOPHEHAD SPEAK RIGHT — Understand the word כן as the Targum does: יאות rightly, properly. God said: Exactly so is this chapter written before me on High (The Law has long since been fixed) (Sifrei Bamidbar 134:1). This tells us that their eye saw what Moses’ eye did not see. (They had a finer perception of what was just in the law of inheritance than Moses had.) (cf. Midrash Tanchuma, Pinchas 8).

Kli Yakar

“You shall surely give them [etc.].” It should have said “lahen” [to them — feminine], and similarly [instead of] among their father’s brothers [the Hebrew] should have said “avihen” [their father — feminine], as it says shortly afterwards and you shall transfer their father’s inheritance to them [feminine]. This is because in matters of inheritance, if he has no son, they stand in place of males for all matters. Therefore it says You shall surely give them [masculine] as if speaking to males, to indicate that they are like males for all matters of inheritance. But afterwards, when it says and you shall transfer, which suggests a language of transgression, or a language of transferring inheritance from tribe to tribe due to them being females, therefore it speaks as if to females: and you shall transfer their father’s inheritance to them [feminine].

Or HaChaim

כן בנות צלפחד דברות, the daughters of Tzelofchod are correct in what they said. The Torah needed to write the word כן in addition to handing down the legal decision. By writing the extra word כן, G'd expressed appreciation of the logic demonstrated by the daughters of Tzelofchod when they had presented their case by basing it on either the law of inheritance or the law of the levirate marriage.
