Genesis 34:2, 24-25

And when Shechem the son of Hamor the Hivite, prince of the country, saw her, he took her and lay with her, and violated her.

And all who went out of the gate of his city heeded Hamor and Shechem his son; every male was circumcised, all who went out of the gate of his city. Now it came to pass on the third day, when they were in pain, that two of the sons of Jacob, Simeon and Levi, Dinah’s brothers, each took his sword and came boldly upon the city and killed all the males.
