ah ok! Well they really aren’t different versions- the newer Bibles are just written in more modern language. Like instead of using ‘Thy’ newer Bibles will say ‘You’ because that is how we speak now. But the prayers mean the same.
For original you’d go back to the earliest known Greek copies but who reads Greek?
All versions are translated directly from the original Greek but put into English there will be some variants because if translating.
The intent and context of all of the versions is the same however.
