17 Moses' father-in-law said to him, "What you are doing is not good. 18 You and the people with you will wear yourselves out, for the thing is too heavy for you; you are not able to perform it alone. 19 Listen now to my voice; I will give you counsel, and God be with you! You shall represent the people before God, and bring their cases to God; 20 and you shall teach them the statutes and the decisions, and make them know the way in which they must walk and what they must do. 21 Moreover choose able men from all the people, such as fear God, men who are trustworthy and who hate a bribe; and place such men over the people as rulers of thousands, of hundreds, of fifties, and of tens. 22 And let them judge the people at all times; every great matter they shall bring to you, but any small matter they shall decide themselves; so it will be easier for you, and they will bear the burden with you. 23 If you do this, and God so commands you, then you will be able to endure, and all this people also will go to their place in peace." 24 So Moses gave heed to the voice of his father-in-law and did all that he had said. 25 Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, of hundreds, of fifties, and of tens. 26 And they judged the people at all times; hard cases they brought to Moses, but any small matter they decided themselves.

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.
