It's quite difficult for me to see Bible as sealed, as there are so many different Bibles.
I already told about the beginning of my doubts when I learnt the different spellings in Torah, but there are less microscopic changes in the whole Bible.
It's a nice pattern to have Ps 117, the shortest chapter, at the exact middle of the 1189 chapters of the whole Christian Bible, but it's true only with the KJV and some other versions coming from the KJV. In LXX and the Vulgata, Ps 117 is the actual Ps 118 of KJV.
I find it a nice pattern too to have the middle between the shortest chapter and the longest one, thinking the gematria of the two middle verses of Ps 119 (or 118) equates the gematria of the two only verses of Ps 117 (or 116).
It seems quite hard to find if there is any genuine numbering of the psalms.
