The third aliyah describes the creation of Chava, Adam's wife, from Adam's body.

In this aliyah is the story of the serpent tricking Chava into eating the forbidden fruit, and Chava subsequently giving the fruit to Adam. As a result they are ashamed of their nakedness, and make clothes. G-d curses the serpent. G-d tells the woman that because of what happened she will experience a more difficult pregnancy and childbirth.

By contrast, the Midrash states that Chava was created and gave birth on the very same day and that her children were born as adults. As a result of Chava's transgression, pregnancy is forty weeks long and children are born as babies, who require much self-sacrifice to raise.

The Midrash further states that Jewish women were given and are entrusted with three special mitzvot to atone for Chava's sin: lighting Shabbos candles, separating the Challah (symbolic of the kashrus of the home), and Taharas Hamishpocha (family purity, G-d's gift to Jewish people benefiting the family's spiritual and physical health).

G-d tells Adam that he will earn his living with difficulty.

(All this happened on Friday. We see also see the strength of the evil inclination (Yezter hora) present on Friday causing arguments, etc. for which we should be careful to avoid.)
