Genesis 2:22

ויבן AND HE FORMED (literally, He built) — as a structure, wide below and narrower above for bearing the child, just as a wheat-store is wide below and narrower above so that its weight should not strain the walls (Berakhot 61a). ויבן את הצלע לאשה AND HE MADE THE RIB INTO A WOMAN — לאשה means that is should become a woman, like (Judges 8:21) “and Gideon made it לאפוד ” i. e., that it should become an ephod.

וַיִּ֩בֶן֩ יְהֹוָ֨ה אֱלֹהִ֧ים ׀ אֶֽת־הַצֵּלָ֛ע אֲשֶׁר־לָקַ֥ח מִן־הָֽאָדָ֖ם לְאִשָּׁ֑ה וַיְבִאֶ֖הָ אֶל־הָֽאָדָֽם׃

and of the side, which the Lord God had taken from the man, He made a woman, and brought her to the man.
