Zeb., Mishnah, Chap. V) , it is, in the first case, piggul (an abomination) , v. Lev. VII, 18, (for which kareth (v. Glos.) is inflicted) , and in the second case, merely ritually unfit (v. Zeb., 29b) . If one has the intention: 'I shall eat a ka-zayith outside th time limit, a ka-zayith outside the place,' or, 'I shall eat a ka-zayith outside the time limit, and a ka-zayith outside the place,' it is the same, according to Rabbi, the first thought ('ka-zayith outside the time') being in either case counted as the main thought, and the sacrifice is therefore piggul, and kareth inflicted; Zeb. 30b. Hence, Rabbi holds that whether and is inserted or omitted, the thoughts are separate, and in our Mishnah also he will hold that and separates the persons (or objects) ; and the statement is therefore particular, and not general.');"><sup>18</sup></span> Come and hear - from his own view:<span class="x" onmousemove="('comment',' An argument against Samuel's interpretation of R.
