'The white bean can you think so!<span class="x" onmousemove="('comment',' We are discussing the vine!');">⁴</span> - Rather, say, its size is that of the white bean. Now, whom do you know to maintain that boser is fruit, but not semadar? The Rabbis.<span class="x" onmousemove="('comment',' For R. Jose maintains that even semadar, which denotes an earlier stage, is fruit.');">⁵</span>
