Genesis 34:13

And the sons of Jacob answered Shechem and Hamor his father deceitfully, and said, because he had defiled Dinah their sister:

Ver. 13. Deceitfully, and said, Because he had, &c.] Therefore they thought they had reason to do as they did. Satan doth so bemist men, many times, that they think they have reason to be mad, and that there is some sense in sinning; when as, indeed, our only wisdom is to keep God's laws; Deu 4:6 all which are founded upon so good reason, that, had God never made them, yet it had been best for us to have practised them.
