I believe the answer is:
aleph
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hebrew leader</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 aleph that I've seen before include "First letter of the Hebrew alphabet" , "letter in Middle East" , "Hebrew character" , "Sign of a beast? A Phoenician" , "Abroad, a" .)
