Text English channel pics featuring king in revolution (9)
I believe the answer is:
scripture
'text' is the definition.
(I have seen 'religious text' mean 'scripture' so perhaps 'text' could also mean 'scripture')
'english channel pics featuring king in revolution' is the wordplay.
'english' becomes 'e' (abbreviation).
'channel' becomes 'rut' (I've seen this before).
'featuring' means one lot of letters goes inside another.
'king' becomes 'r' (r is abbreviation for rex).
'in revolution' says the letters should be written backwards.
'e'+'rut'+'pics'='erutpics'
'erutpics' enclosing 'r' is 'erutpircs'.
'erutpircs' written backwards gives 'SCRIPTURE'.
(Other definitions for scripture that I've seen before include "Sacred writing" , "Holy Writ" , "Sacred writings as in Old and New Testament" , "Sacred writings of a religion" , "religious works" .)
