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.
