<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">biblical boatbuilder</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 noah that I've seen before include "Animal rescuer" , "A host of animals" , "First collector of animals?" , "Biblical arkwright" , "zoo keeper" .)
