1 Timothy 1:3-5

3As I urged you when I was going to Macedonia, remain at Ephesus so that you may charge certain persons not to teach any different doctrine,

4nor to devote themselves to myths and endless genealogies, which promote speculations rather than the stewardship from God that is by faith.

5The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith.
