מִֽי־פָעַ֣ל וְעָשָׂ֔ה קֹרֵ֥א הַדֹּר֖וֹת מֵרֹ֑אשׁ אֲנִ֤י יְהוָה֙ רִאשׁ֔וֹן וְאֶת־אַחֲרֹנִ֖ים אֲנִי־הֽוּא׃
װער האָט דאָס געמאַכט און געטאָן? דער װאָס רופֿט אױס די דורות פֿון אָנהײב. איך ה׳ בין דער ערשטער, און מיט די לעצטע בין איך דער אײגענער.
Rashi
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
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
and with the last ones I am He Also with you, the last sons, I will be, and I will aid you.
