Genesis 34:15 WEB

¹³  The sons of Jacob answered Shechem and Hamor his father with deceit, and spoke, because he had defiled Dinah their sister,

¹⁴  and said to them, 'We can't do this thing, to give our sister to one who is uncircumcised; for that is a reproach to us.

¹⁵  Only on this condition will we consent to you. If you will be as we are, that every male of you be circumcised;

¹⁶  then will we give our daughters to you, and we will take your daughters to us, and we will dwell with you, and we will become one people.

¹⁷  But if you will not listen to us, to be circumcised, then we will take our sister,{Hebrew has, literally, 'daughter'} and we will be gone.'
