NSB(i)
5 Servants, be obedient to those who according to the flesh are your masters, with fear and trembling, in sincerity of your heart, as to Christ.
6 This should not be in the way of eye service, as men-pleasers; but as servants of Christ, doing the will of God from a complete heart;
7 with goodwill doing service, as to God, and not to men.
