Usage does not come into it, that's just adding to the definition to suit a bias position, or want.
Even with your corruption, the verse 17:5 does NOT literally place Jesus back with the Father, before the world was.
But just working with this corruptions, lets us let the Bibleroll it over shall we,as in the context you are falsely using it in = lies by implication. 2 Tim 1:9 -He hassaved usandcalled usto a holy calling, not because of our works, but by Hisown purposeand by the grace Hegranted usin Christ Jesus before time eternal.
Now lets LOOK at what these people can now RIGHTFULLY ask the Father for and YOU cannot deny and maintain truth; And now, O Father, glorify thou me with thine own selfwith the glory whichIhad with thee before the world was.
