A New Testament hill-dweller (3)

I believe the answer is:

ant

'hill-dweller' is the definition.
(I've seen this before)

'a new testament' is the wordplay.
'new testament' becomes 'nt'.
'a'+'nt'='ANT'

(Other definitions for ant that I've seen before include "Worker on the hill" , "Emmet or pismire" , "Six-footer" , "Small busy insect" , "Dec's long-time partner" .)

I've seen this clue in The Globe and Mail.
