Level with First Lady (3)
I believe the answer is:
eve
'first lady' is the definition.
(first woman in the Bible)
'level with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'EVE' can be found hidden inside 'level'.
(Other definitions for eve that I've seen before include "Previous day" , "First lady from the night before" , "Adam's partner" , "Later in the day, in short" , "Adam's wife" .)
