Ephesians 6:9

“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.” (Ephesians 6:5–9, ESV)
