King David's wayward son
I believe the answer is:
'king david's wayward son' is the definition.
(I've seen this in another clue)
This is all the clue.
(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" .)
