Ephesians 6:5-8

Williams(i) 5 You slaves must practice obedience to your earthly masters, with reverence and awe, with sincerity of heart, as you would obey Christ, 6 not serving them as though they were watching you, but as true slaves of Christ, trying to carry out the will of God. 7 Heartily and cheerfully keep on working as slaves, as though it were for the Lord and not for men, 8 for you know that everyone, slave or free, will get his reward from the Lord for anything good he has done.
