Genesis 34:13-25

13But because Shechem had defiled their sister Dinah, Jacob’s sons answered him and his father Hamor deceitfully. 14“We cannot do such a thing,” they said. “To give our sister to an uncircumcised man would be a disgrace to us. 15We will consent to this on one condition, that you become circumcised like us—every one of your males. 16Then we will give you our daughters and take your daughters for ourselves. We will dwell among you and become one people. 17But if you will not agree to be circumcised, then we will take our sister and go.”

18Their offer seemed good to Hamor and his son Shechem. 19The young man, who was the most respected of all his father’s household, did not hesitate to fulfill this request, because he was delighted with Jacob’s daughter.

20So Hamor and his son Shechem went to the gate of their city and addressed the men of their city: 21“These men are at peace with us. Let them live and trade in our land; indeed, it is large enough for them. Let us take their daughters in marriage and give our daughters to them. 22But only on this condition will the men agree to dwell with us and be one people: if all our men are circumcised as they are. 23Will not their livestock, their possessions, and all their animals become ours? Only let us consent to them, and they will dwell among us.”

24All the men who went out of the city gate listened to Hamor and his son Shechem, and every male of the city was circumcised.

25Three days later, while they were still in pain, two of Jacob’s sons (Dinah’s brothers Simeon and Levi) took their swords, went into the unsuspecting city, and slaughtered every male.
