Genesis 34:15

American Standard Version (1901)

Only on this condition will we consent unto you: if ye will be as we are, that every male of you be circumcised;

See the chapter Copy

I beseech you, brethren, become as I am, for I also am become as ye are. Ye did me no wrong:

and said unto them, We cannot do this thing, to give our sister to one that is uncircumcised; for that were a reproach unto us.

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.

This is my covenant, which ye shall keep, between me and you and thy seed after thee: every male among you shall be circumcised.
