Verse 20. - Thou shalt teach them ordinances and laws. Or, "statutes and laws," as in ver. 16. It is not quite clear how these differ. Some regard "statutes" as connected with religion, and laws as regulations with respect to civil and social matters. Others explain the first as "specific" and the second as "general enactments." The way wherein they must walk. The general line of conduct which all axe bound to pursue. The work that they must do. The special task which each has to perform individually.

18:13-27 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.And thou shalt teach them ordinances and laws,.... Both with respect to things civil and religious, which he should receive from God:

and shalt show them the way wherein they must walk; the path of faith and duty, the way of truth, holiness, and righteousness:

and the work that they must do; both with respect to God, and one another, the various duties and exercises of religion, everything relating to their moral, religious, and civil conduct.
