כָּל־צֹ֤אן קֵדָר֙ יִקָּ֣בְצוּ לָ֔ךְ אֵילֵ֥י נְבָי֖וֹת יְשָׁרְת֑וּנֶךְ יַעֲל֤וּ עַל־רָצוֹן֙ מִזְבְּחִ֔י וּבֵ֥ית תִּפְאַרְתִּ֖י אֲפָאֵֽר׃
All the flocks of Kedar shall be gathered together unto thee, The rams of Nebaioth shall minister unto thee; They shall come up with acceptance on Mine altar, And I will glorify My glorious house.
Rashi on Isaiah
the rams of Nebaioth Heb. אֵילֵי, rams of Nebaioth [after Jonathan].
Ibn Ezra on Isaiah
ישרתונך Shall minister unto thee, that is, shall be at thy service; comp. לשרת to do service (Ex. 35:19), which is used of the cloth for covering the holy vessels during the journey.
Ibn Ezra on Isaiah
על רצון על מזבחי═על רצון מזבחי With acceptance on my altar.8Usually one preposition is connected with several nouns, but in one and the same meaning; here this is not the case. על רצון means with acceptance, or for acceptance; על מזבחי upon my altar. But, in fact, the repetition of the preposition is not required here at all, since עלה governs also the accusative; comp. Gen. 49:4; Num. 13:17.
