1 Timothy 6:3-5; 1 Timothy 6:20-21

3 So teach and exhort. If any one is a teacher of any other kind of doctrine, and refuses assent to wholesome instructions--those of our Lord Jesus Christ--and the teaching that harmonizes with true godliness,

4 he is puffed up with pride and has no true knowledge, but is crazy over discussions and controversies about words which give rise to envy, quarrelling, revilings, ill-natured suspicions,

5 and persistent wranglings on the part of people whose intellects are disordered and they themselves blinded to all knowledge of the truth; who imagine that godliness means gain.

20 O Timothy, guard the truths entrusted to you, shunning irreligious and frivolous talk, and controversy with what is falsely called `knowledge';

21 of which some have spoken boastfully in connexion with the true faith, and have erred. Grace be with you all.
