Prophet captured by Grandma Moses (4)

I believe the answer is:

amos

'prophet' is the definition.
(biblical prophet)

'captured by grandma moses' is the wordplay.
'captured by' says the answer is hidden in the clue.
'AMOS' is hidden in the letters of 'grandma moses'.

(Other definitions for amos that I've seen before include "30th OT book" , "Part of bible" , "man" , "American wild dog" , "Old Testament prophet" .)

I've seen this clue in The Sun.
