Genesis 34:21-24

“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. 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. 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.” 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.
