Genesis 34:25-27

25Three days after the men were circumcised, they still had a lot of pain. Then two of Jacob's sons attacked Shechem's men with their swords. None of the men were ready to fight. Jacob's two sons were Simeon and Levi, Dinah's brothers. They killed every male in the city.

26They killed Hamor and his son Shechem. Then they took Dinah from Shechem's house and they left.

27Jacob's other sons also saw that the men of the city were dead. So they took everything that they wanted from the city. They did that because it was the place where Shechem had done a very bad thing against their sister.
