Genesis 34:21-24

“These men are at peace with us; let them dwell in the land and trade in it, for behold, the land is large enough for them. Let us take their daughters as wives, and let us give them our daughters. Only on this condition will the men agree to dwell with us to become one people—when every male among us is circumcised as they are circumcised. Will not their livestock, their property and all their beasts be ours? Only let us agree with them, and they will dwell with us.” And all who went out of the gate of his city listened to Hamor and his son Shechem, and every male was circumcised, all who went out of the gate of his city.
