<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">arrow case</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for quiver that I've seen before include "Tremble - case for arrows" , "Receptacle in which archer keeps arrows" , "Tremble and shake, or receptacle for arrows" , "Arrow case" , "Wobble" .)
