Genesis 34:25-26

But three days later, when their wounds were still sore, two of Jacob’s sons, Simeon and Levi, who were Dinah’s full brothers, took their swords and entered the town without opposition. Then they slaughtered every male there, including Hamor and his son Shechem. They killed them with their swords, then took Dinah from Shechem’s house and returned to their camp.
