Genesis 34:21-23

21These men are peaceable with us; therefore let them dwell in the land, and trade in it; for the land, behold, it is large enough for them; let us take their daughters to us for wives, and let us give them our daughters. 22Only on this condition will the men consent to us to dwell with us, to be one people, if every male among us shall be circumcised, as they are circumcised. 23Shall not their cattle and their substance and every beast of theirs be ours? only let us consent to them, and they will dwell with us.
