Extended line, English, for you in the Bible? (7)
I believe the answer is:
lengthy
'extended' is the definition.
(similar in meaning)
'line english for you in the bible?' is the wordplay.
'line' becomes 'l'.
'english' becomes 'eng'.
'for you in the bible?' becomes 'thy' (word for 'your' used in the King James Bible).
'l'+'eng'+'thy'='LENGTHY'
(Other definitions for lengthy that I've seen before include "Prolonged" , "Taking up a lot of time" , "Protracted" , "Prolix - tedious" , "Rather long" .)
