Genesis 34:15-25

15 But on this condition we will consent to you: If you will become as we are, if every male of you is circumcised,
16 then we will give our daughters to you, and we will take your daughters to us; and we will dwell with you, and we will become one people.
17 But if you will not heed us and be circumcised, then we will take our daughter and be gone."
18 And their words pleased Hamor and Shechem, Hamor's son.
19 So the young man did not delay to do the thing, because he delighted in Jacob's daughter. He was more honorable than all the household of his father.
20 And Hamor and Shechem his son came to the gate of their city, and spoke with the men of their city, saying:
21 "These men are at peace with us. Therefore let them dwell in the land and trade in it. For indeed the land is large enough for them. Let us take their daughters to us as wives, and let us give them our daughters.
22 Only on this condition will the men consent to dwell with us, to be one people: if every male among us is circumcised as they are circumcised.
23 Will not their livestock, their property, and every animal of theirs be ours? Only let us consent to them, and they will dwell with us."
24 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.
25 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.
