Dina bas Yaakov was the daughter of Leah and Yaakov Avinu. When Dina went out to see the daughters of Shechem she was seen by Chamor, the son of Shechem who proceeded to kidnap her. In revenge, Levi and Shimon, two of the brothers, attacked and destroyed the city of of Shechem. According to some opinions, she later married Iyov when the family moved to Egypt.

Dina is buried in Arbel, Israel along with two of her brothers, most likely Reuvain and Shimon.

It was known to all the Imahos that Yaakov would beget twelve sons (future tribes) in order to parallel the twelve archetypal personalities that could be found in the Jewish Nation. When Leah became pregnant with her seventh son, she realized that Rachel would remain with Yosef as her single son, making her inferior to the maidservant wives, Bilha and Zilpa, as each already had two children. Leah felt that she could not leave her sister Rachel in this predicament. She began praying that the fetus should become a girl. Her prayers were answered. When a girl was born she named her Dina after the din - judgment - that she had issued upon herself.

Dina had a daughter named Osnat from the incident with Shechem. This illegitimate child was fostered out by the family and was transported by angels to Egypt where she was adopted by Potifar. Osnat later married Yosef.
