As to the OP (title) question, I've found something that is SIMILAR to those pointing out how:
-- the FIRST and the LAST letters of the Bible (in the Hebrew and the Greek) spell (together)
"bn" (the Hebrew word meaning "SON"), so that both the FIRST and the LAST must be considered together
in order to see it (i.e. both the OT and the NT)...

"v" in Greek is our English
"n" -

... so what I found was something
similar to this ^ , but I'm not prepared to share it here.
[IOW, the evidence itself (in that example, for instance) is plain, in the text]
