Ephesians 6:7

5 Servants, be obedient to those who according to the flesh are your masters, with fear and trembling, in singleness of your heart, as to Christ,

6 not in the way of service only when eyes are on you, as men pleasers, but as servants of Christ, doing the will of God from the heart,

7 with good will doing service as to the Lord and not to men,

8 knowing that whatever good thing each one does, he will receive the same good again from the Lord, whether he is bound or free.

9 You masters, do the same things to them, and give up threatening, knowing that he who is both their Master and yours is in heaven, and there is no partiality with him.
