What are the connotations of "Kiryas Chutzos"?
Rashi: It means a town full of market-places, teeming with men, women and children (of Mo'av) - as if to say 'See and take pity on all these people; that they should not be destroyed!'
Targum Yonasan: It means a major town that belonged to Sichon called Birosha where the streets are walled. 1
See Na'ar Yonasan, who does not understand what Targum Yonasan is trying to tell us.
