What is the question "ha'Ani Ashbir v'Lo Olid"?
Rashi: Will I bring the woman to the birthing stone, and I will not open her womb to take out the fetus?! I.e. will I begin the matter and I cannot finish it 1 ?!
Malbim: This answers "will she give birth to a nation at once?!" (8) Since I brought her to the birthing stone, via the contractions that I brought on them, which are preparation for birth, surely I will cause the birth of the Klal!
Radak: This cannot be. It compared Tziyon to a woman who gives birth. If I will bring Tziyon to the birthing stone - the war of Gog and Magog - I will make her give birth. The birth is the salvation.
Why does it say "Im Ani ha'Molid v'Atzarti"?
Rashi: I cause every Yoledes to give birth - did I stop now?
Radak: Until that time, I make lands of Nochrim give birth. Will I stop then?! The grandeur and honor will be to Yisrael alone.
Radak citing Targum Yonasan: I, Elokim, created the world...
Malbim: This answers "will the land have contractions in one day?!" (8) I cause to give birth, and I stop some. Surely I will open the womb of barren women to make them give birth, for the Klal. Therefore, the contractions will come to the Klal of the nation. I will not do part of the matter, rather, all of it.
