Rab Judah stated: 'At first I used to examine blood, but since the mother of my son Isaac told me, "We do not bring the first drop to the Rabbis because it is dirty", I refuse to see it.<span class="x" onmousemove="('comment',' Because the colour changes and though the second drop may be one of clean blood it could not establish a woman's cleanness if the first drop, which she did not present for examination, was one of unclean blood. ');">¹⁶</span>
