26They killed Hamor and his son Shechem with the edge of the sword, and took Dinah out of Shechem’s house [where she was staying], and left.

27Then Jacob’s [other] sons came upon those who were killed and looted the town, because their sister had been defiled and disgraced.

28They took the Canaanites’ flocks and their herds and their donkeys, and whatever was in the city and in the field;

29they looted all their wealth, and [took captive] all their children and their wives, even everything that was in the houses.

30Then Jacob said to Simeon and Levi, “You have ruined me, making me a stench to the inhabitants of the land, the Canaanites and the Perizzites! My men are few in number, and the men of the land will band together against me and attack me; I shall be destroyed, I and my household.”

31But they said, “Should he [be permitted to] treat our sister as a prostitute?”
