Titus 3:9-11

21st Century King James Version

⁹ But avoid foolish questions, and genealogies, and contentions, and strivings about the law, for they are unprofitable and vain.

¹⁰ If a man is a heretic, after the first and second admonition reject him,

¹¹ knowing that such as he is subverted and sinneth, being condemned by himself.
