Ephesians 6:5-9

5Bondservants, obey your earthly masters with fear and trembling, with a sincere heart, as you would Christ,

6not by the way of eye-service, as people-pleasers, but as bondservants of Christ, doing the will of God from the heart,

7rendering service with a good will as to the Lord and not to man,

8knowing that whatever good anyone does, this he will receive back from the Lord, whether he is a bondservant or is free.

9Masters, do the same to them, and stop your threatening, knowing that he who is both their Master and yours is in heaven, and that there is no partiality with him.
