Genesis 34:13-17

13But Jacob’s sons answered Shechem and his father Hamor with deceit, because he had defiled Dinah their sister. 14They said to them, “We cannot do this thing, to give our sister to 1one who is uncircumcised, for that would be a disgrace to us. 15Only on this condition will we consent to you: if you will become like us, in that every male of you be circumcised, 16then we will give our daughters to you, and we will take your daughters for ourselves, and we will 2live with you and become one people. 17But if you will not listen to us to be circumcised, then we will take our daughter and go.”
