<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">genesis matriarch</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for leah that I've seen before include "her elder sister" , "Rachel's sister" , "Jacob's first wife (Bible)" , "Hale (anag) - wife of Jacob" , "First wife of Jacob" .)
