Genesis 34:21-24

“These men are peaceful and friendly with us; so let them live in the land and do business in it, for the land is large enough [for us and] for them; let us take their daughters for wives and let us give them our daughters [in marriage]. But only on this condition will the men consent to our request that they live among us and become one people: that every male among us become circumcised just as they are circumcised. Will not their cattle and their possessions and all their animals be ours [if we do this]? Let us consent [to do as they ask], and they will live here with us.” And every [Canaanite] man who went out of the city gate listened and considered what Hamor and Shechem said; and every male who was a resident of that city was circumcised.
