Titus 3:8-11 New American Standard Bible (NASB)
8 This is a trustworthy statement; and concerning these things I want you to speak confidently, so that those who have believed God will be careful to engage in good deeds. These things are good and profitable for men. 9 But avoid foolish controversies and genealogies and strife and disputes about the Law, for they are unprofitable and worthless. 10 Reject a factious man after a first and second warning, 11 knowing that such a man is perverted and is sinning, being self-condemned.
