כֵּ֗ן בְּנ֣וֹת צְלָפְחָד֮ דֹּבְרֹת֒ נָתֹ֨ן תִּתֵּ֤ן לָהֶם֙ אֲחֻזַּ֣ת נַחֲלָ֔ה בְּת֖וֹךְ אֲחֵ֣י אֲבִיהֶ֑ם וְהַֽעֲבַרְתָּ֛ אֶת־נַחֲלַ֥ת אֲבִיהֶ֖ן לָהֶֽן׃
슬로브핫 딸들의 말이 옳으니 너는 반드시 그들의 아비의 형제 중에서 그들에게 기업을 주어 얻게 하되 그 아비의 기업으로 그들에게 돌릴지니라
Rashi on Numbers
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).
Or HaChaim on Numbers
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.
Rabbeinu Bahya
כן בנות צלפחד דוברות, “the daughters of Tzelofchod speak properly;” the word כן here is in essence the same as באמת, truthfully, correctly. Sifri 134 comments: “hail to the people whose words are applauded by G’d.”
