Talk that’s held between both sides and God’s messenger (7)

I believe the answer is:

gabriel

I'm a little stuck... Click here to teach me more about this clue!

'messenger' is the definition.
(I've seen this before)

'talk that's held between both sides and god's' is the wordplay.
I cannot quite understand how this works, but
'that's' could be 'ie' and 'ie' is found within the answer.
'sides' could be 'rl' (I've seen this in other clues) and 'rl' is located in the leftover letters.
The remaining letters 'gab' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for gabriel that I've seen before include "Boy" , "Chief guard of Paradise" , "Man'" , "Archangel who plays the trumpet" , "musician" .)
