Ephesians 6:5-9 RSVA

5 Slaves, be obedient to those who are your earthly masters, with fear and trembling, in singleness of heart, as to Christ;
6 not in the way of eye-service, as men-pleasers, but as servants of Christ, doing the will of God from the heart,
7 rendering service with a good will as to the Lord and not to men,
8 knowing that whatever good any one does, he will receive the same again from the Lord, whether he is a slave or free.
9 Masters, do the same to them, and forbear threatening, knowing that he who is both their Master and yours is in heaven, and that there is no partiality with him.
