If I wanted to say ‘look at Matthew chapter 20 verses 25-28’ would it be: ‘gade nan Matye chapit 20 vèsè 25 rive nan 28’? And for ‘look at John 3:16’ could I say ‘gade nan Jan twa sèz’ or do I need to say ‘gade nan Jan chapit twa, vèsè sèz’?

'gade nan Matye chapit 20 vèsè 25 rive nan 28' is correct.
and it will also be correct if you said:
'gade nan Matye chapit 20 vèsè 25 a 28'

‘gade nan Jan twa sèz' and ‘gade nan Jan chapit twa, vèsè sèz’ are both correct. It is isn't necessary to say the latter for people to understand.

Kenbe la :)
