Biblical queen's land (5)
I believe the answer is:
sheba
'biblical queen's land' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sheba that I've seen before include "Its queen went to visit Solomon" , "Biblical queendom" , "Biblical Queen of . . . . . visited King Solomon" , "Solomon's guest" , "Ancient name of South Yemen" .)
