Wife of Jacob (4)
I believe the answer is:
leah
'wife of jacob' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leah that I've seen before include "Jacobs first wife (Gen.29)" , "Rachel's sister" , "Jacob's first wife (Gen. 29)" , "her elder sister" , "First wife of Jacob" .)
