מִֽי־פָעַ֣ל וְעָשָׂ֔ה קֹרֵ֥א הַדֹּר֖וֹת מֵרֹ֑אשׁ אֲנִ֤י יְהוָה֙ רִאשׁ֔וֹן וְאֶת־אַחֲרֹנִ֖ים אֲנִי־הֽוּא׃
Wer hat es gewirkt und vollbracht? Der die Menschengeschlechter berief vom Anbeginn. Ich, der Herr, bin der Erste, und bei den Spätesten bin ich derselbe.

Who worked and did for him all this? He Who called the generations from the beginning, to Adam, He did this also for Abraham.
Ibn Ezra on Isaiah
עשה Hath prepared.9A. V., And hath done. Comp. לעשות to dress (Gen. 18:7). Who has done this? God has done it, who is calling the generations from the beginning, before they come into existence; who knows all future generations, and cites each of them to appear in its right time.
Rashi on Isaiah
I, the Lord, am first to perform wonders and to aid.
