2 Timothy 3:14-17

14But as for you, acontinue in what you have learned and have firmly believed, knowing from whom
The Greek for  whom is plural
you learned it
15and how cfrom childhood you have been acquainted with dthe sacred writings, ewhich are able to make you wise for salvation through faith in Christ Jesus. 16 fAll Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17that gthe man of God
That is, a messenger of God (the phrase echoes a common Old Testament expression)
may be complete, iequipped jfor every good work.
