Reference for Bava Batra 111:6

מאי חצובא אמר רב יהודה אמר רב שבו תיחם יהושע לישראל את הארץ

Raba said: Even if there is a block of wood between [he is not penalised]. Raba's view here [that such a block can form a partition] conforms with his other view that a 'place' in respect of Sabbath has the same meaning as a 'place' in respect of divorces.<span class="x" onmousemove="('comment',' If a man transfers his courtyard to his wife and then throws her a get into it and it lights on such a block, she is not divorced, because the block is not included in the courtyard transferred to the wife. Hence here he is not penalised. ');">⁶</span>
