Colossians 3:22-4:1

²² Bondservants, obey in everything those who are your earthly masters, not by way of eye-service, as people-pleasers, but with sincerity of heart, fearing the Lord. ²³ Whatever you do, work heartily, as for the Lord and not for men, ²⁴ knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ. ²⁵ For the wrongdoer will be paid back for the wrong he has done, and there is no partiality. 

4 Masters, treat your bondservants justly and fairly, knowing that you also have a Master in heaven.
