Warrior of 1 Samuel (7)
I believe the answer is:
goliath
'warrior of 1 samuel' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for goliath that I've seen before include "David laid him low with slingshot" , "Giant Philistine laid low by David" , "Giant, David's victim" , "Giant Philistine felled by David" , "Giant Philistine killed by David" .)
