1 Timothy 1:4
Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.
1 Timothy 4:1

1 Timothy 4:16
Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.
