Genesis 34:25-29

Now on the third day [after the circumcision], when all the men were [terribly] sore and in pain, two of Jacob’s sons, Simeon and Levi, Dinah’s [full] brothers, took their swords, boldly entered the city [without anyone suspecting them of evil intent], and they killed every male. They 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. Then Jacob’s [other] sons came upon those who were killed and looted the town, because their sister had been defiled and disgraced. They took the Canaanites’ flocks and their herds and their donkeys, and whatever was in the city and in the field; they looted all their wealth, and [took captive] all their children and their wives, even everything that was in the houses.
