Exodus 18:26

And they judged the people at all seasons, Moses having charged and obligated them to do their work with all considerate impartiality. The hard causes they brought unto Moses, as the final court of appeal, but every small matter they judged themselves. It is not the will of God that His servants should needlessly wear themselves out in the service of the Church. It is well-pleasing to Him that the work of the Church, both in general and in the individual congregations, be distributed according to the gifts which He has given. Thus the work will result in the benefit of all.
