NHEB(i)
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 people-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 people;
