But if you will not agree to be circumcised, then we will take our sister and go.”
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.
Commenting on Genesis 34:6-17
But if ye will not hearken to us to be circumcised,.... Will not agree to this condition, circumcision: then will we take our daughter; by force, as the Targum of Jonathan adds: and we will be gone: depart from this part of the country, and go elsewhere.
Then will we take our daughter, and we will he gone - It is natural to suppose that the tribe of Hamor was very inconsiderable, else they would not have sought an alliance with the family of Jacob, and have come so readily into a painful, disgraceful measure, without having either the sanction of Divine authority or reason; for it does not appear that the sons of Jacob urged either.
