Holy Land lake (7)
I believe the answer is:
galilee
'holy land lake' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for galilee that I've seen before include "Northern part of ancient Palestine" , "Biblical sea, as I allege" , "Biblical Sea west of the Jordan" , "Biblical sea known to Jesus" , "Sea between Israel and Jordan" .)
