Peyton's younger brother (3)
I believe the answer is:
eli
'peyton's younger brother' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eli that I've seen before include "Highest priest at Shiloh" , "Religious character" , "Man's name" , "Shiloh priest (Bible)" , "Biblical teacher of Samuel" .)
