Adam Clarke on 1 Peter 2:18

Servants, be subject - See the notes on Eph 6:5; Col 3:22 (note); and Tit 2:9 (note).

With all fear - With all submission and reverence.

The good and gentle - Those who are ever just in their commands, never requiring more work than is necessary or proper, and always allowing sufficient food and sufficient time.

The froward - Σκολιοις· The crooked, perverse, unreasonable morose, and austere. Your time belongs to your master; obey him in every thing that is not sinful; if he employs you about unreasonable or foolish things, let him answer for it. He may waste your time, and thus play the fool with his own property; you can only fill up your time: let him assign the work; it is your duty to obey.
