וַיֹּאמֶר֮ הָֽאָדָם֒ זֹ֣את הַפַּ֗עַם עֶ֚צֶם מֵֽעֲצָמַ֔י וּבָשָׂ֖ר מִבְּשָׂרִ֑י לְזֹאת֙ יִקָּרֵ֣א אִשָּׁ֔ה כִּ֥י מֵאִ֖ישׁ לֻֽקֳחָה־זֹּֽאת׃
האָט דער מענטש געזאָגט: דאָס מאָל איז דאָס אַ בײן פֿון מײַנע בײנער, און פֿלײש פֿון מײַן פֿלײש; די דאָזיקע זאָל גערופֿן װערן פֿרױ, װײַל פֿון אַ מאַן איז גענומען געװאָרן די דאָזיקע.
Rashi

Chizkuni
זאת הפעם, “this time;” he meant that this time the male’s partner was made of his own flesh. But he realised that this was a one time occurrence and would not repeat itself. Henceforth, instead of woman emanating from man, man would emanate from woman. (her womb).
Rashbam
זאת הפעם עצם מעצמי, “only this time will man’s wife be made of his own bone and flesh; in the future things will be reversed, a male will come forth from a female, not as this time.”
