פירוש על בראשית 34:1

בת לאה THE DAUGHTER OF LEAH — so Scripture calls her. Why not the daughter of Jacob? But just because she “went out” she is called Leah’s daughter, since she, too, was fond “of going out” (Genesis Rabbah 80:1), as it is said (30:16) “and Leah went out to meet him”. With an allusion to her they formulated the proverb: “Like mother, like daughter”.

THE DAUGHTER OF LEAH, WHOM SHE HAD BORNE UNTO JACOB. The reason [Scripture specifies the daughter of Leah] is to state that she was the sister of Simeon and Levi, who were envious for her sake and avenged her cause. And Scripture mentions further, whom she had borne unto Jacob, in order to allude to the fact that all the brothers were envious for her.

ותצא דינה, because Yaakov had pitched his tent outside the city limits of Shechem. She left that compound to enter the town.
