John Calvin on Genesis 34:3

3. And his soul clave unto Dinah. Moses intimates that she was not so forcibly violated, that Shechem having once abused her, treated her with contempt, as is usual with harlots; for he loved her as a wife; and did not even object to be circumcised that he might have her; but the fervor of lust had so prevailed, that he first subjected her to disgrace. And therefore although he embraced Dinah with real and sincere attachment, yet, in this want of self-government, he grievously sinned. Shechem “spoke to the heart” of the maid, that is, he addressed her courteously, to allure her to himself by his bland speeches: whence it follows, that when she was unwilling and resisted, he used violence towards her.
