Numbers 26:65

There was not left a man of them, to wit, of those who then murmured and rebelled against God, as plainly appears, both because this threatening and punishment is confined to those transgressors, and because otherwise this had not been true; for of those that were then numbered there were now left Eleazar and Ithamar, and possibly many of the Levites, and some others, who being not guilty of that sin, did not partake of their judgment. Caleb and Joshua are mentioned here, as also Num 14, not by way of exception, as if these were murmurers, which is utterly denied, Numbers 14:24, but by way of opposition, to signify that they, though they were two of the spies, and companions of them who were the chief authors and ringleaders of that mutiny, yet they kept themselves from their sin, and therefore God kept them from their plague and destruction, as also he did some others for the same reason.
