Genesis 34:25-27

25Now 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.

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.
