אוצר, מה אוצר זה רחב מלמטה וקצר מלמעלה כדי לקבל את הפירות ⁠— אף האשה רחבה מלמטה וקצרה מלמעלה כדי לקבל את הולד.

of a storehouse. Just as a storehouse is built wide on the bottom and narrow on top, in order to hold produce without collapsing, so too a woman is created wide on the bottom and narrow on top, in order to hold the fetus.

״ויביאה אל האדם״⁠ — מלמד שעשה הקדוש ברוך הוא שושבינות לאדם הראשון, מכאן לגדול שיעשה שושבינות לקטן ואל ירע לו.

The Talmud cites an exposition of the end of the previously cited verse: “And brought her to the man” (Genesis 2:22). This verse teaches that God was Adam the first man’s best man, attending to all his wedding needs and bringing his wife to him. From here we learn that a greater individual should serve as a best man for a lesser individual and should not feel bad about it as something beneath his dignity.

ולמאן דאמר פרצוף, הי מינייהו סגי ברישא? אמר רב נחמן בר יצחק: מסתברא דזכר סגי ברישא, דתניא: לא יהלך אדם אחורי אשה בדרך, ואפילו היא אשתו. נזדמנה על הגשר יסלקנה לצדדין. וכל העובר אחורי אשה בנהר ⁠— אין לו חלק לעולם הבא.

The Talmud asks: And according to the one who says that Eve was a face or side of Adam, which one of them walked in front? Rav Naḥman bar Yitzḥak said: It is reasonable to say that the male walked in front, as this is proper behavior, as it was taught in a baraita: A man should not walk behind a woman on a path, even if she is his wife. If she happens upon him on a bridge, he should walk quickly in order to catch up to her and consequently move her to his side, so that she will not walk before him. And anyone who walks behind a woman in a river, where she has to lift up her skirt in order to cross, has no share in the World-to-Come.
