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)...
-- https://biblehub.com/text/genesis/1-1.htm "bə-rê-šîṯ " (first word--first letter)
-- "v" in Greek is our English "n" - https://biblehub.com/text/revelation/22-21.htm (see last word--last letter)
... 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]
