Great men should not only study to be useful themselves, but contrive to make others useful. Exodus 18

Exodus 18:17 may mark the beginning of representative government as we know it today. Moses for some time had been mediating disputes and quarrels between members of his flock when his father-in-law, Jethro, saw that the burden of judgement was taking its toll on Moses. There was only a loose system of laws so I imagine disputes were numerous. Moses needed help and Jethro had the answer:

Exodus 18:19 "Listen now to me and I will give you some advice, and may God be with you. You must be the people’s representative before God and bring their disputes to him. 20 Teach them his decrees and instructions, and show them the way they are to live and how they are to behave. 21 But select capable men from all the people—men who fear God, trustworthy men who hate dishonest gain—and appoint them as officials over thousands, hundreds, fifties and tens. 22 Have them serve as judges for the people at all times, but have them bring every difficult case to you; the simple cases they can decide themselves. That will make your load lighter, because they will share it with you. 23 If you do this and God so commands, you will be able to stand the strain, and all these people will go home satisfied.”

And again Presbyterian minister Matthew Henry has some insight:

"Here is the great zeal and the toil of Moses as a magistrate. Having been employed to redeem Israel out of the house of bondage, he is a further type of Christ, that he is employed as a lawgiver and a judge among them. If the people were as quarrelsome one with another as they were with God, no doubt Moses had many causes brought before him. This business Moses was called to; it appears that he did it with great care and kindness. The meanest Israelite was welcome to bring his cause before him. Moses kept to his business from morning to night. Jethro thought it was too much for him to undertake alone; also it would make the administration of justice tiresome to the people. There may be over-doing even in well-doing. Wisdom is profitable to direct, that we may neither content ourselves with less than our duty, nor task ourselves beyond our strength. Jethro advised Moses to a better plan. Great men should not only study to be useful themselves, but contrive to make others useful. Care must be taken in the choice of the persons admitted into such a trust. They should be men of good sense, that understood business, and that would not be daunted by frowns or clamours, but abhorred the thought of a bribe. Men of piety and religion; such as fear God, who dare not to do a base thing, though they could do it secretly and securely. The fear of God will best fortify a man against temptations to injustice. Moses did not despise this advice. Those are not wise, who think themselves too wise to be counselled."
