Moses
Genesis 34:15ESV·traditional attribution

Only on this condition will we agree with you—that you will become as we are by every male among you being circumcised.

Matthew Henry Presbyterian

Jacob's sons, when they heard of the injury done to Dinah, showed a very great resentment of it, influenced perhaps rather by jealousy for the honour of their family than by a sense of virtue. Many are concerned at the shamefulness of sin that never lay to heart the sinfulness of it.

John Gill Reformed Baptist

But in this will we consent unto you,.... Upon the following condition, that Dinah should be given in marriage: if ye will be as we be, that every male of you be circumcised; as the sons of Jacob were, according to the command given to Abraham their great grandfather, Gen 17:10.

Geneva Bible Notes Reformed

But in this will we consent unto you: If ye will be as we [be], that every male of you be circumcised; (e) Their fault is even greater since they made religion a disguise for their deceit.
