Here, 1. Hamor and Shechem gave consent themselves to be circumcised, Gen 34:18, Gen 34:19. To this perhaps they were moved, not only by the strong desire they had to bring about this match, but by what they might have heard of the sacred and honourable intentions of this sign, in the family of Abraham, which, it is probable, they had some confused notions of, and of the promises confirmed by it, which made them the more desirous to incorporate with the family of Jacob, Zac 8:23. Note, Many who know little of religion, yet know so much of it as makes them willing to join themselves with those that are religious. Again, If a man would take upon him a form of religion to gain a good wife, much more should we embrace the power of it to gain the favour of a good God, even circumcise our hearts to love him, and, as Shechem here, not defer to do the thing. 2. They gained the consent of the men of their city, Jacob's sons requiring that they also should be circumcised. (1.) They themselves had great influences upon them by their command and example. Note, Religion would greatly prevail if those in authority, who, like Shechem, are more honourable than their neighbours, would appear forward and zealous for it. (2.) They urged an argument which was very cogent (Gen 34:23), Shall not their cattle and their substance be ours? They observed that Jacob's sons were industrious thriving people, and promised themselves and their neighbours advantage by an alliance with them; it would improve ground and trade, and bring money into their country. Now, [1.] It was bad enough to marry upon this principle: yet we see covetousness the greatest matchmaker in the world, and nothing designed so much, with many, as the laying of house to house, and field to field, without regard had to any other consideration. [2.] It was worse to be circumcised upon this principle. The Shechemites will embrace the religion of Jacob's family only in hopes of interesting themselves thereby in the riches of that family. Thus there are many with whom gain is godliness, and who are more governed and influenced by their secular interest than by any principle of their religion.

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. And they are threatened here that if they do not agree to be circumcised, Dinah shall be taken from them, and restored to her family; and this is probably what the Shechemites saw they had not power at present to prevent.

And their words pleased Hamor, and Shechem Hamor's son. The condition proposed was acceptable to them both, and they agreed to comply with it; Hamor, because of the great love he had for his son; Shechem, because of the great love he had for Dinah.

Genesis 34:19

gen 34:19
gen 34:19
gen 34:19And the young man deferred not to do the thing,.... To be circumcised himself, and to get all the males of the city circumcised; he delayed not a moment, but made all the haste he could to get it accomplished:

because he had delight in Jacob's daughter; he really loved her, and delighted in her person and company: it was not the effect of a brutish lust, but a true affection he bore to her, that he desired her in marriage:

and he was more honourable than all the house of his father; for though he had done a base thing in defiling Jacob's daughter, yet in this he was honourable, that he sought to marry her, and to do any thing that was in his power to recompence the injury; and he was honourable in keeping covenant and compact with men; and was honest, upright, and sincere, to fulfil the condition imposed on him, and he had agreed to, as well as he was in greater esteem among the citizens than any of his father's house, which made it the more easy to him to get their consent to be circumcised; they having a very high and honourable opinion of him, and ready to oblige him in anything they could.

The sons of Jacob answered--The honor of their family consisted in having the sign of the covenant. Circumcision was the external rite by which persons were admitted members of the ancient Church. But that outward rite could not make the Shechemites true Israelites; and yet it does not appear that Jacob's sons required anything more. Nothing is said of their teaching the people to worship the true God, but only of their insisting on their being circumcised; and it is evident that they did not seek to convert Shechem, but only made a show of religion--a cloak to cover their diabolical design. Hypocrisy and deceit, in all cases vicious, are infinitely more so when accompanied with a show of religion; and here the sons of Jacob, under the pretense of conscientious scruples, conceal a scheme of treachery as cruel and diabolical as was, perhaps, ever perpetrated.
