אֲנִ֧י יְהוָ֛ה קְרָאתִ֥יךָֽ בְצֶ֖דֶק וְאַחְזֵ֣ק בְּיָדֶ֑ךָ וְאֶצָּרְךָ֗ וְאֶתֶּנְךָ֛ לִבְרִ֥ית עָ֖ם לְא֥וֹר גּוֹיִֽם׃
Я, Господь, призвал тебя в праведности, и взял тебя за руку, и хранил тебя, и поставил тебя для завета народа, для света народов;
Ibn Ezra on Isaiah
I, the Lord, have called thee, etc. The Lord in these words addresses the prophet upon his own concerns.
Rashi on Isaiah
and I formed you Heb. וְאֶצָּרְךָ. When I formed you (כְּשֶׁיְצַרְתִּיךָ), this was My thought, that you return My people to My covenant and to enlighten them.
