Reference for Bava Batra 110:5

רבא אמר אפילו לענין שבת דתניא הוציא חצי גרוגרת לרשות הרבים והניחה וחזר והוציא חצי גרוגרת אחרת בהעלם אחד חייב בשני העלמות פטור

Raba, however, says that they form a partition even in respect of Sabbath, as it has been taught: If a man takes out half a dry fig into a public place,<span class="x" onmousemove="('comment',' If anyone takes out from a private to a public place an article not smaller than a fig and sets it down there, he is liable to punishment for breaking the Sabbath. ');">⁹</span> and puts it down and then takes out another half a dry fig, in one spell of unawareness that it was Sabbath, he is penalised [for breaking the Sabbath],<span class="x" onmousemove="('comment',' Because he has taken out one whole fig. ');">¹⁰</span>
