Wickedness accepted by rich man: time to sell up (9)
I believe the answer is:
disinvest
'sell up' is the definition.
(eg to withdraw an investment by selling shares)
'wickedness accepted by rich man time' is the wordplay.
'wickedness' becomes 'sin' (synonyms).
'accepted by' means one lot of letters goes inside another.
'rich man' becomes 'dives' (rich man in the Bible).
'time' becomes 't' (abbreviation).
'sin' put inside 'dives' is 'disinves'.
'disinves'+'t'='DISINVEST'
'to' acts as a link.
(Other definitions for disinvest that I've seen before include "Dispose of shares" , "Remove money" .)
