Waters that had big part in Bible? (3,3)
I believe the answer is:
red sea
'part in bible?' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'waters that had big' is the wordplay.
'waters' becomes 'Reds' (Red is an example).
'that had big' becomes 'ea' (I can't explain this - if you can you should give a lot more credence to this answer).
'reds'+'ea'='RED SEA'
Can you help me to learn more?
(Other definitions for red sea that I've seen before include "It divided for Moses" , "It's linked to the Mediterranean by the Suez Canal" , "Water bordering Egypt" , "It parted for Moses and his followers" , "What the Suez canal links with the Mediterranean" .)
