Level with first woman (3)
I believe the answer is:
eve
'first woman' 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 "Day before; girl's name" , "Adam's wife" , "Woman in a happy place" , "Day before; first woman" , "First mate" .)
