創世記 34:31 註釋：Rashi, Radak, Sforno & Or HaChaim

הכזונה implies as one unprotected.

?ויאמרו הכזונה, is Shechem to be allowed to treat our sister as if she were a harlot, and we should not avenge the shame she was subjected to?

?הכזונה, only a harlot does not have anyone standing up in her defense, avenging violence done to her. יעשה, “shall the people who you are afraid of rising up against us be allowed to get away with such conduct? את אחותנו, who was not a harlot. It is incumbent upon us to avenge her disgrace. Once the inhabitants of the region will understand this they will have no reason to attack us.”

אחותנו The Targum renders it as an accusative — ית אחתנא “our sister”,) so that the meaning is: Should one (be permitted to) make our sister become as a woman who has no-one to protect her (Genesis Rabbah 80:12).
