Genesis 34:14-16

saying, “Our culture will not allow us to consent to our sister Dinah marrying someone who is uncircumcised, for that would be a disgrace to us. We would only approve of the marriage on one condition: you must circumcise every male among you and become as we are. Then we will allow our daughters to marry your sons and your daughters to marry our sons. And we will live among you and become one people.
