1 Timothy 6:1-2 RSV

1 Let all who are under the yoke of slavery regard their masters as worthy of all honor, so that the name of God and the teaching may not be defamed.
2 Those who have believing masters must not be disrespectful on the ground that they are brethren; rather they must serve all the better since those who benefit by their service are believers and beloved. Teach and urge these duties.
