1 Timothy 1:3-7 RSV

3 As I urged you when I was going to Macedonia, remain at Ephesus that you may charge certain persons not to teach any different doctrine,
4 nor to occupy themselves with myths and endless genealogies which promote speculations rather than the divine training that is in faith;
5 whereas the aim of our charge is love that issues from a pure heart and a good conscience and sincere faith.
6 Certain persons by swerving from these have wandered away into vain discussion,
7 desiring to be teachers of the law, without understanding either what they are saying or the things about which they make assertions.
