Ummm you are simply posting the same verse over and over. The question is NOT what is Psalm 118:8... the question is what verse is the 'middle' of the Bible. You aren't showing that they are the middle verse. Nor is showing how 'middle verse is defined.' Is it page number? Is it number of words before and after?
Are you including versions of the Bible that include added text?
Your posting doesn't indicate anything about "the middle verse."
REGARDING the changes in the Bible - try this recent book by Biblical Scholar Bart Ehrman:
