Rashi on Genesis 19:12/רש"י על בראשית י״ט:י״ב

1עד מי לך פה WHOM HAST THOU YET HERE — The evident sense of the verse is: whom else have you in this city besides thy wife and daughters who are at home with you.

2חתן ובניך ובנותיך SON-IN-LAW, THY SONS AND THY DAUGHTERS — If you have a son-in-law, sons or daughters take them out of this place.

3ובניך THY SONS means the sons of your married daughters. The Midrashic explanation of עוד YET is: since they have perpetrated so disgraceful an act, can you yet be so bold (more literally, “can you yet open your mouth”) to speak in defence of them? — for the whole night through he had been talking in favor of them. To obtain this explanation you must read: עוד מי לך פֶּה Have you yet a mouth! (instead of פֹּה here) (Genesis Rabbah 50:5).
