Genesis 34:13-17

13Jacob’s sons answered Shechem and Hamor his father deceitfully, because Shechem had defiled and disgraced their sister Dinah.

14They said to them, “We cannot do this thing and give our sister [in marriage] to one who is not circumcised, because that would be a disgrace to us.

15But we will consent to you only on this condition: if you will become like us, in that every male among you consents to be circumcised,

16then we will give our daughters to you [in marriage], and we will take your daughters for ourselves, and we will live with you and become one people.

17But if you do not listen to us and refuse to be circumcised, then we will take our daughter [Dinah] and go.”
