Genesis 34:2, 24, 25

When Shechem son of Hamor the Hivite, the ruler of that area, saw her, he took her and raped her.

All the men who went out of the city gate agreed with Hamor and his son Shechem, and every male in the city was circumcised.

Three days later, while all of them were still in pain, two of Jacob’s sons, Simeon and Levi, Dinah’s brothers, took their swords and attacked the unsuspecting city, killing every male.
