Jacob's first wife
I believe the answer is:
leah
'jacob's first wife' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for leah that I've seen before include "her elder sister" , "She married Jacob" , "Heal (anag) - girl" , "Jacob's first wife (Gen. 29)" , "Jacobs first wife (Gen.29)" .)
