Biblical giant (7)
I believe the answer is:
goliath
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">biblical giant</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 goliath that I've seen before include "David slew him with a slingshot (7)" , "Philistine giant slain by David" , "David laid him low with slingshot" , "Giant Philistine felled by David" , "Giant Philistine laid low by David" .)
