think the most likely option is that the Potter motto was first taken from the Bible in Latin, and at some point after the completion of the King James Bible (in the 1600s) the motto was updated to English.
The motto is in Old English in the story, presumably dating from the time of the Peverells. It may have been taken from the bible verse, but then your own argument raises the question, why didn’t they write their motto in Latin?

The Old English is the prophecy, not the motto.
Right, I stand corrected.
