Ephesians 6:5-8

BLB(i) 5 Slaves, obey the earthly masters with fear and trembling, in sincerity of your heart as to Christ, 6 not with eye-service as men-pleasers, but as servants of Christ, doing the will of God from the heart, 7 rendering service with good will as to the Lord and not to men, 8 knowing that each one, whatever good he might have done, this he will receive back from the Lord, whether he is slave or free.
