Since the Torah does not use an expression of eating (which always implies a k'Zayis), how much must one eat to nullify Inuy?
Rashi (in Yoma, 80b): The Shi'ur Inuy is a thick Koseves (a large species of date). 1
Rashi (Ibid.): The amount required to attain 'Yishuv ha'Da'as' (a settled mind). See Torah Temimah, note 90.
What are the implications of "asher Lo Se'uneh"?
Yoma, 80b: It precludes someone who eats something hat harms him from Kareis. 1
See Torah Temimah, note 91.
What are the implications of ?Ki Chol ha?Nefesh asher Lo Se?uneh Venichr?sah??
Yerushlmi Yoma, 8:1: It implies that, although there are five Inuyim that are prohibited on Yom Kipur, one is only Chayav Kareis for eating and drinking ? which affect the Nefesh. 1
Refer to Vayikra, 16:29:2:2.
