How do I write the bible verse reference. For example: 1 John 1:9. Do you write it 1 Jan 1:9 and do you place the reference at the beginning or end of the verse?

Yes you write it as: 1 Jan 1:9
You say it as : En Jan En vèsè nèf
Most people write it at the end of the verse in Bible Study, but if your group is trying to memorize the verse (saying it out loud), then they'll 'chant' the verse reference first.
