Rashi on Genesis 2:23/רש"י על בראשית ב׳:כ״ג

1זאת הפעם THIS NOW — This teaches that Adam endeavoured to find a companion among all cattle and beasts, but found no satisfaction except in Eve (Yevamot 63a).

2לזאת יקרא אשה כי מאיש וגו THIS SHALL BE CALLED WOMAN, BECAUSE THIS WAS TAKEN OUT OF MAN — Here we have a kind of play upon words (the words אשה and איש sounding similar): hence we may learn that the language used at the time of the Creation was the Holy Tongue (Hebrew) (Genesis Rabbah 18:4).
