Genesis 34:24-31

All the people who had come to the city gate heard this. They agreed with Hamor and Shechem, and every man was circumcised. Three days later the men who were circumcised were still in pain. Two of Jacob’s sons, Simeon and Levi (Dinah’s brothers), took their swords and made a surprise attack on the city, killing all the men there. They killed Hamor and his son Shechem and then took Dinah out of Shechem’s house and left. Jacob’s sons came upon the dead bodies and stole everything that was in the city, to pay them back for what Shechem had done to their sister. So the brothers took the flocks, herds, and donkeys, and everything in the city and in the fields. They took every valuable thing the people owned, even their wives and children and everything in the houses. Then Jacob said to Simeon and Levi, “You have caused me a lot of trouble. Now the Canaanites and the Perizzites who live in the land will hate me. Since there are only a few of us, if they join together to attack us, my people and I will be destroyed.” But the brothers said, “We will not allow our sister to be treated like a prostitute.”
