I'm so curios about when Jehovah's witnesses started to use/mention "Proverbs 4:18" for changing their doctrines or briefs.
Did they start it from early 1800's by Russell ? or next generation of JW's --- J.F. Rutherford? N.H. Knorr??
Please let me know if you know any record(s) or evidence(s). Thank you.
