Bar change, Lord embraces Gabriel (9)
I believe the answer is:
archangel
'gabriel' is the definition.
(I've seen this before)
'bar change lord embraces' is the wordplay.
'embraces' says the answer is hidden in the clue (I've seen 'embraced' mean this).
'ARCHANGEL' can be found hidden inside 'bar change lord'.
(Other definitions for archangel that I've seen before include "Highest ranking member of the celestial hierarchy" , "Divine messenger - Russian port" , "Russian port on the White Sea" , "What we call a port" , "foreign port" .)
