1 Timothy 6:1-5

All who are under the yoke as bond-servants (slaves) are to regard their own masters as worthy of honor and respect so that the name of God and the teaching [about Him] will not be spoken against. Those who have believing masters are not to be disrespectful toward them because they are brothers [in Christ], but they should serve them even better, because those who benefit from their kindly service are believers and beloved. Teach and urge these [duties and principles]. If anyone teaches a different doctrine and does not agree with the sound words of our Lord Jesus Christ, and with the doctrine and teaching which is in agreement with godliness (personal integrity, upright behavior), he is conceited and woefully ignorant [understanding nothing]. He has a morbid interest in controversial questions and disputes about words, which produces envy, quarrels, verbal abuse, evil suspicions, and perpetual friction between men who are corrupted in mind and deprived of the truth, who think that godliness is a source of profit [a lucrative, money-making business—withdraw from them].
