King David's wayward son (7)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">king david's wayward son</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 absalom that I've seen before include "Son of King David (Bible)" , "King David's rebellious son" , "David's third son (OT)" , "David's boy" , "King's rebellious son" .)
