Genesis 34:15, King James Version

In context

14 And 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:

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

16 Then 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.
