Titus 3:9-12

But avoid foolish controversies and genealogies and strife and disputes about the Law, for they are unprofitable and worthless. Reject a factious man after a first and second warning, knowing that such a man is perverted and is sinning, being self-condemned. When I send Artemas or Tychicus to you, make every effort to come to me at Nicopolis, for I have decided to spend the winter there.
