וְאַל־יֹאמַ֣ר בֶּן־הַנֵּכָ֗ר הַנִּלְוָ֤ה אֶל־יְהוָה֙ לֵאמֹ֔ר הַבְדֵּ֧ל יַבְדִּילַ֛נִי יְהוָ֖ה מֵעַ֣ל עַמּ֑וֹ וְאַל־יֹאמַר֙ הַסָּרִ֔יס הֵ֥ן אֲנִ֖י עֵ֥ץ יָבֵֽשׁ׃ (ס)
Et qu’il ne dise pas, le fils de l’étranger qui s’est rallié à l’Éternel: "Certes, le Seigneur m’exclura de son peuple!" Et qu’il ne dise pas, l’eunuque: "Hélas! Je ne suis qu’un arbre desséché!"
Sforno
מתה אנכי, a figure of speech, meaning the same as הן אני עץ יבש, “here I am a dried out tree,” in Isaiah 56,3.
Rashbam
ונירם, they were driven from their places. The word is similar to נחרם, they were banished. The construction is parallel to נטה and ונט. The word is derived from the root ירה, hence וניר, “vanir.” The vocalisation of vanirom means the same as if the Torah had written vanireym. We find a similar construction in Isaiah 56,3 yavdilani, which is the same as yavdileyni. Also in Exodus 14,11 lehotziani is the same as lehotzieyni. If we were to follow Onkelos’ translation, the vocalisation should have been veniram instead of vaniram.
Rashbam
יאהבני, the vowel patach under the letter ב is equivalent to the letter having been vocalised with a tzeyreh. We have a similar construction in Isaiah 56,3 where the word yavdilani means the same as if the prophet had written yavdileyni.
