Ephesians 6:5-9

5Servants, be obedient unto them that according to the flesh are your masters, with fear and trembling, in singleness of your heart, as unto Christ; 6not in the way of eyeservice, as men-pleasers; but as servants of Christ, doing the will of God from the heart; 7with good will doing service, as unto the Lord, and not unto men: 8knowing that whatsoever good thing each one doeth, the same shall he receive again from the Lord, whether he be bond or free. 9And, ye masters, do the same things unto them, and forbear threatening: knowing that he who is both their Master and yours is in heaven, and there is no respect of persons with him.
