19 Hearken now unto my voice, I will give thee counsel, and God be with thee: be thou for the people to God-ward, and bring thou the causes unto God: 20 and thou shalt teach them the statutes and the laws, and shalt show them the way wherein they must walk, and the work that they must do. 21 Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating unjust gain; and place such over them, to be rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens: 22 and let them judge the people at all seasons: and it shall be, that every great matter they shall bring unto thee, but every small matter they shall judge themselves: so shall it be easier for thyself, and they shall bear [the burden] with thee. 23 If thou shalt do this thing, and God command thee so, then thou shalt be able to endure, and all this people also shall go to their place in peace. 24 So Moses hearkened to the voice of his father-in-law, and did all that he had said. 25 And Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens. 26 And they judged the people at all seasons: the hard causes they brought unto Moses, but every small matter they judged themselves. 27 And Moses let his father-in-law depart; and he went his way into his own land.

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.
