Ephesians 6:5-9 CEBA

5 As for slaves, obey your human masters with fear and trembling and with sincere devotion to Christ.
6 Don't work to make yourself look good and try to flatter people, but act like slaves of Christ carrying out God's will from the heart.
7 Serve your owners enthusiastically, as though you were serving the Lord and not human beings.
8 You know that the Lord will reward every person who does what is right, whether that person is a slave or a free person.
9 As for masters, treat your slaves in the same way. Stop threatening them, because you know that both you and your slaves have a master in heaven. He doesn't distinguish between people on the basis of status.
