Ephesians 6:5-9New Revised Standard Version (NRSV)
Slaves and Masters
5 Slaves, obey your earthly masters with fear and trembling, in singleness of heart, as you obey Christ; 6 not only while being watched, and in order to please them, but as slaves of Christ, doing the will of God from the heart. 7 Render service with enthusiasm, as to the Lord and not to men and women, 8 knowing that whatever good we do, we will receive the same again from the Lord, whether we are slaves or free.
9 And, masters, do the same to them. Stop threatening them, for you know that both of you have the same Master in heaven, and with him there is no partiality.
