Genesis 34 opens with Dinah going out to visit the women of the surrounding country, and Shechem, son of the local ruler Hamor, seeing her, taking her, and lying with her by force. The text then complicates the episode rather than resolving it simply: Shechem, having assaulted her, is described as being drawn to her in love, speaking tenderly to her, and asking his father to arrange the marriage. Hamor approaches Jacob and his sons with an offer of full intermarriage and trade between the two peoples, and Shechem himself offers any bride price they name, however great.
Jacob's sons answer with deceit, telling Hamor and Shechem that intermarriage is possible only if every male of the city is circumcised. Hamor and Shechem agree and persuade the men of their city to accept it, and on the third day afterward, while the men are still in pain from the procedure, Simeon and Levi, Dinah's full brothers, enter the city and kill every male, including Hamor and Shechem, and take Dinah out of Shechem's house. The other brothers then plunder the city, taking flocks, wealth, and the surviving women and children.
Jacob's response, once the killing is done, is not moral outrage but strategic fear, he tells Simeon and Levi they have made him odious to the surrounding peoples and put his household at risk of destruction. Simeon and Levi answer with the chapter's final line: should our sister be treated like a prostitute. Dinah herself speaks not a single recorded word anywhere in the chapter that bears her name.
