Context

13And the sons of Jacob answered Shechem and Hamor his father deceitfully, and said, because he had defiled Dinah their sister:

14And they said unto them, We cannot do this thing, to give our sister to one that is uncircumcised; for that were a reproach unto us:

15But in this will we consent unto you: If ye will be as we be, that every male of you be circumcised;

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

17But if ye will not hearken unto us, to be circumcised; then will we take our daughter, and we will be gone.
