Thou shalt be able to endure.--Comp. Exodus 18:18, where the inability of Moses to endure, unless he made some change, was strongly asserted.
And all this people shall also go to their place in peace.--The people, i.e., will go on their way to Canaan peacefully and contentedly, without suffering the inconvenience to which they are now subject.
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.
