Everyone who shall confess me (pas hos an homologēsei en emoi). Just like Mat 10:32 except the use of an here which adds nothing. The Hebraistic use of en after homologeō both here and in Matthew is admitted by even Moulton (Prolegomena, p. 104).
The Son of man (ho huios tou anthrōpou). Here Mat 10:32 has k'agō (I also) as the equivalent.
