Genesis 34:1

And Dinah, the daughter of Leah, which she bare unto Jacob, went out to see the daughters of the land. Dinah had probably been born in the fourteenth year of Jacob's service in Mesopotamia. She was, like Simeon and Levi, who are so prominent in this story, a child of Jacob and Leah. About ten years had now elapsed since the family had come, first to Succoth and then to Shechem, and Dinah was a young woman, the girls in the Orient reaching maturity at an early age. Dissatisfied, perhaps, with the supposed curbing of her personal liberty in her father's house, Dinah went out to make the acquaintance of the Canaanitish girls and to visit with them.
