כִּֽי־כַבֵּ֤ד אֲכַבֶּדְךָ֙ מְאֹ֔ד וְכֹ֛ל אֲשֶׁר־תֹּאמַ֥ר אֵלַ֖י אֶֽעֱשֶׂ֑ה וּלְכָה־נָּא֙ קָֽבָה־לִּ֔י אֵ֖ת הָעָ֥ם הַזֶּֽה׃
porque grandemente te honrarei, e farei tudo o que me disseres; vem pois, rogo-te, amaldiçoar-me este povo.
Rashi on Numbers
כי כבד אכבדך מאד FOR I WILL HONOR THEE EXCEEDINGLY — Exceedingly: more than you have ever received as a fee in the past (cf. Rashi Numbers 21:27) will I now give you (Midrash Tanchuma, Balak 6).
Tur HaArokh
כי כבד אכבדך, “for I will greatly honour you.” He meant that he would pay him handsomely.
Siftei Chakhamim
More than you have received in the past. For if not so, how would he know how to honor him? Perhaps the entire honor that he would give him would still not come to half of the honor due to him.
