But it was not so, it actually stood at the head of the two rows of tables,<span class="x" onmousemove="('comment',' And was thus nearest to the Holy of Holies. Moreover, as the ground of the Temple sloped downwards from west to east, the table of Moses, being nearest the west side, was indeed on a higher elevation than the other tables.');"><sup>7</sup></span>
