Ephesians 6:5–9

5 Bondservants, obey your earthly masters with fear and trembling, with a sincere heart, as you would Christ, 6 not by the way of eye-service, as people-pleasers, but as bondservants of Christ, doing the will of God from the heart, 7 rendering service with a good will as to the Lord and not to man, 8 knowing that whatever good anyone does, this he will receive back from the Lord, whether he is a bondservant or is free. 9 Masters, 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.
