Titus:3:8-9
kjv@Titus:3:8 @ This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.
kjv@Titus:3:9 @ But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
