Divine nourishment (5)
I believe the answer is:
manna
'divine nourishment' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for manna that I've seen before include "Food provided by God for the Israelites in the wilderness" , "Food God gave to Moses" , "Heavenly grub?" , "Delicious food" , "Old Testament food (from heaven?)" .)
