When the latter appeared before Abaye he<span class="x" onmousemove="('comment',' Abaye. ');">¹⁹</span> said to him: Go and take it for yourself. Now, the majority [in that case] consisted of Israelites. Hence it must be concluded that the <i>halachah</i> is in accordance with R. Simeon b. Eleazar even where the majority are Israelites! — [The position in regard to] a vulture is different — for it is like the tide of the sea.<span class="x" onmousemove="('comment',' The owner is sure to have given up the hope of recovering the loss.
