To their place - i. e. to Canaan, which is thus recognized by Jethro as the appointed and true home of Israel. Compare Numbers 10:29-30.

If thou shalt do this thing, and God command thee - Though the measure was obviously of the utmost importance, and plainly recommended itself by its expediency and necessity; yet Jethro very modestly leaves it to the wisdom of Moses to choose or reject it; and, knowing that in all things his relative was now acting under the immediate direction of God, intimates that no measure can be safely adopted without a positive injunction from God himself. As the counsel was doubtless inspired by the Divine Spirit, we find that it was sanctioned by the same, for Moses acted in every respect according to the advice he had received.

If thou shall do this thing,.... Hearken to the advice given, and put it in execution, by choosing out of the people, and placing over them, judges qualified, as directed: and God command thee so; for he did not desire him to follow his advice any further than it appeared to be according to the will of God, which he doubted not he would inquire about; and if he found it was agreeable to it, and should pursue it:

then thou shall be able to endure; to continue in his office and post, and hold on for years to come, God granting him life and health; whereas otherwise, in all human probability, he must waste and wear away apace:

and all this people shall also go to their place in peace; having had their cases heard and tried, and their differences adjusted to satisfaction; and quick dispatch being made, they would return to their tents or places of abode in much peace of mind, and sit down contented with the determination made, and pleased that the lawsuit was not protracted to any unreasonable length of time. Jarchi interprets all this people, of Aaron, Nadab, and Abihu, and the seventy elders that came with him, as if they by this means would be eased, and so pleased with it.

If thou shalt do this thing, and God command thee so, then thou shalt be able to endure, and all this people shall also go to their place in peace.

23. If thou shalt do this thing, &c.-Jethro's counsel was given merely in the form of a suggestion; it was not to be adopted without the express sanction and approval of a better and higher Counsellor; and although we are not informed of it, there can be no doubt that Moses, before appointing subordinate magistrates, would ask the mind of God, as it is the duty and privilege of every Christian in like manner to supplicate the divine direction in all his ways.

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.
