Titus 3:9-14

But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain. A man that is an heretick after the first and second admonition reject; knowing that he that is such is subverted, and sinneth, being condemned of himself.
When I shall send Artemas unto thee, or Tychicus, be diligent to come unto me to Nicopolis: for I have determined there to winter. Bring Zenas the lawyer and Apollos on their journey diligently, that nothing be wanting unto them. And let our's also learn to maintain good works for necessary uses, that they be not unfruitful.
