Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather. For he that is called in the Lord, being a servant, is the Lord's freeman: likewise also he that is called, being free, is Christ's servant.
1 Corinthians 7:21-22
Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ.
Ephesians 6:5
Servants, obey in all things your masters according to the flesh; not with eyeservice, as menpleasers; but in singleness of heart, fearing God.
Colossians 3:22
Masters, give unto your servants that which is just and equal; knowing that ye also have a Master in heaven.
Colossians 4:1
Let as many servants as are under the yoke count their masters worthy of all honor, that the name of God and his doctrine be not blasphemed. And they that have believing masters, let them not despise them, because they are brethren; but rather do them service, because they are faithful and beloved, partakers of the benefit. These things teach and exhort. If any man teach otherwise ... he is proud, knowing nothing.... From such withdraw thyself.
1 Timothy 6:1-5
Servants, obey in all things your masters according to the flesh; not with eyeservice, as menpleasers; but in singleness of heart, fearing God.
Titus 2:9-10
Servants, be subject to your masters with all fear, not only to the good and gentle, but also to the froward.
1 Peter 2:18
