Water-carrier met a prophet (5)
I believe the answer is:
hosea
'prophet' is the definition.
(I've seen this before)
'water-carrier met a' is the wordplay.
'water carrier' becomes 'hose' (I've seen this in another clue).
'met' says to put letters next to each other.
'hose'+'a'='HOSEA'
(Other definitions for hosea that I've seen before include "Hebrew prophet; book of Bible" , "Book of the Old Testament - a shoe (anag)" , "Book writer" , "OT prophet" , "OT prophet/book" .)
