Be sure that fellow is attorney for chapel (8)
I believe the answer is:
bethesda
'chapel' is the definition.
(I've seen this before)
'be sure that fellow is attorney' is the wordplay.
'be sure' becomes 'bet' ('I bet that...' means 'I am sure that...').
'that fellow' becomes 'hes' (I can't justify this - if you can you should give a lot more credence to this answer).
'is attorney' becomes 'DA' (abbreviation for District Attorney).
'bet'+'hes'+'da'='BETHESDA'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for bethesda that I've seen before include "Chapel" , "Healing pool (Jerusalem)" , "church" .)
