What does "Dodaso" mean?
Targum Onkelos: It means 'the wife of one's paternal uncle.
Targum Yonasan: It means the wife of one's uncle. 1
Presumably, irrespective of whether he is a paternal or a maternal uncle.
What are the implications pf "Aririm Yamusu" (or "Yih'yu" - See following Pasuk)?
Rashi (citing Targum Onkelos), Ramban, Rashbam and Targum Yonasan: It means that they will die childless, even it t they already have children. 1
Rashi: In which case they will bury them.
Bearing in mind the Pasuk "Ish be'Chet'o Yumasu" (Devarim 24:16), how can "Aririm" be telling us that children who are already born will die for the sins of their father?
Maharal in Gur Aryeh: Only children who are minors at the time of the father's sin will bear the punishment of the father's sin, since we find that minors are indeed punished for their father's sins (see Shabbos 32b, Kesuvos 105b, Rashi Koheles 5:5)
Panim Yafos (Vayikra 24:16): If the child sins b'Shogeg, but the father performed the same sin b'Meizid, then the child will be held accountable as if he too sinned b'Meizid even if he is grown up, because of his father's ill intent. But if the child did not sin at all, he will not be punished for his father's sin.
Why does the Torah insert "Aririm" specifically by Dodaso and by Eishes Achiv (in the next Pasuk)?
