Genesis 34:21-23

21“These men are friendly toward us,” they said. “Let them live in our land and trade in it; the land has plenty of room for them. We can marry their daughters and they can marry ours. 22But the men will agree to live with us as one people only on the condition that our males be circumcised, as they themselves are. 23Won’t their livestock, their property and all their other animals become ours? So let us agree to their terms, and they will settle among us.”
