1 Timothy 6:1-2

11All who are under the yoke as slaves are to regard their own masters as worthy of all honor 2so that the name of God and our doctrine will not be 3spoken against. 2Those who have believers as their masters must not be disrespectful to them because they are 4brothers or sisters, but must serve them all the more, because those who 5partake of the benefit are believers and beloved. 6Teach and 7preach these principles.
