As king, he was superior to Rodney (5)

I believe the answer is:
herod
'as king he was superior to rodney' is the definition.
The definition suggests a singular noun which matches the answer.
'he was superior to rodney' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'rod' and 'rod' is found within the answer.
The remaining letters 'he' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for herod that I've seen before include "Royal baby-killer" , "King of Judea in the time of Jesus" , "Biblical king of Judaea" , "Biblical king of Judea" , "Cruel king" .)
