It's no stretch - just part of regular speak
Got a knock at the door this morning - two guys (?elders) - first up I was shown a wt booklet and the opening line is, "We'd like to show you something from the bible. It's not from us, it's from the bible"- all the while holding up the little wt book.
Smiling, I said that I've read many bibles, and "I don't believe that's from the bible - you just think it is" - they didn't stay another second.
