1 Timothy 6:1-3

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)
