Biblical character -- I put in 'apostle' erroneously (7,6)
I believe the answer is:
pontius pilate
'biblical character' is the definition.
The definition suggests a singular noun which matches the answer.
'i put in apostle erroneously' is the wordplay.
'erroneously' indicates anagramming the letters.
'i'+'put'+'in'+'apostle'='iputinapostle'
'iputinapostle' anagrammed gives 'PONTIUS PILATE'.
Can you help me to learn more?
(Other definitions for pontius pilate that I've seen before include "Governor" , "Roman procurator of Judaea who ordered Jesus's crucifixion" , "Roman general" , "Roman official who authorised Jesus' crucifixion" , "Jesus's judge" .)
